Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable i-e naturally replenished. Renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 2.7% and are growing very rapidly. The share of renewables in electricity generation is around 18%, with 15% of global electricity coming from hydroelectricity and 3% from new renewable.

Renewable energy is also referred as “clean energy” or “green energy”. This is because renewable energy produces minimal amounts of pollution. It is also termed as alternative energy. Renewable energy puts energy in our hands by offering increased local control of energy production, helping to ensure low prices and increase the security of our energy supply. Renewable energy also provides environmental benefits such as helping to improve local air quality and reducing our impact on the land, water and climate system. Increased use of renewable energy will also help boost local economies through job creation.

Renewable energy that is the hottest of the focal point in current times cannot be used up and it does not generate pollution. Sustainability means that we make sure we meet our energy needs and ensure the health of the planet for future generations. Eventually, we will run out of nonrenewable energy supplies and the pollution caused by using these energy sources is already becoming a serious problem. The sooner we switch to using renewable energy, the cleaner the air we breathe and water we drink will be. Among these renewable energy resources the foldable wind generator is also one of the innovations but there is still a question mark on its development.

Eolic design has been introduced in foldable wind generator class but it is uncertain as to whether it’s capable or not. The Eolic looks great and is an incredible idea, but can it actually create enough energy to power anything and is it durable enough to actually hold its ground in a wind strong enough to create electricity? Still it’s an ambitious idea and we have to sit back and see its viability.

The light weight material which has been used in designing Eolic does not seem to withstand the high winds to generate the power. The designers’ concepts behind the foldable wind generator are to be able to supply power on the go in areas that do not have access to electricity. Whether it was the beginning of a construction project or a community that lacked electricity, these portable units could be put up to supply the necessary power to that specific area. However, this being a portable unit, that luxury is not possible. While the overall ambitions of the designers may be a bit unrealistic, the Eolic foldable wind generator can still serve a purpose.

Off and on, we experience watching some portable solar devices advertized which provide lighting and or used for other small household purposes, this device should come up in parity. If it actually works in these scenarios, it could truly bring wind power into the picture as a primary renewable energy. The device would surely give an added advantage over the solar power as it could work 24/7. On the other hand, they could also be sold as a package to ensure constant renewable energy on the go.

As the demand for the renewable energy resources is increasing, so is the number of consultants offering their services and expertise. If you intend to install some renewable energy plant at your house or office, you would surely need the help of some consultant that would guide you about the right way of doing so, so that you can take maximum advantage of your plan.

How a consultant can be helpful?

A good renewable energy consultant in this regard would be better capable of guiding you about the aspects that you need to consider while installing the renewable energy plant, he can offer you his expertise in the amount of finances that you would be required to have, and many other options that you have in this regard.

As the consultancy market is growing for the installation of renewable energy plants, in order to have the best consultant for you, see which other companies the consultant have worked with. The experienced the consultant would be, the better planning he or she would provide to you in this regard.

Considering cost issues

Cost is an important issue to be looked over, if you are planning to get the services of a consultant for installing a renewable energy project at a small level, you may have face comparatively high costs as you would be required to pay for a bigger project. The reason is not that for small projects the consultants ask for higher rates, however, comparing to the cost of overall projects their costs seems quite high. So, when you are opting for the renewable energy projects, you need to sort out the cost issues in detail.

When it is necessary to rely upon professional consultants?

You may proceed at your own with the small projects, but initiating with the large projects you would surely need to rely upon the professional consultants so the investment can be made while keeping in mind all the important aspects of the project.

Lastly, when it is about searching a suitable consultant, you are left with two choices to go for one, that are, either to find some one living in your vicinity, or go for searching some suitable consultant online.

When we talk about natural gas, most of the people think that, instead of other fuels, by using it, they are just helping out in improving the environment, as burning it is perceived to produce less amount of carbon. Though using natural gas as fuel produces far less amount of carbon, yet we cannot claim that burning it excessively is helpful for the environment in one way or the other. The only thing that we need to consider is that how do we generate power by utilizing it.

When natural gas is burnt in order to produce electricity, it of course emits harmful substance for the environment. If you can notice, large power stations use great amount of natural gas everyday to produce energy that add up harmful emissions to the environment. The process poses considerable dangers to the ozone layer which has already started deteriorating.

The negative impact of burning gas in power stations

A lay man may ask the question that how using natural gas can harm the environment, well, as mentioned above, though this kind of energy does produce a little amount of environmentally dangerous emissions, yet by slowly and steadily it is harming the environment we are living in. even the small amount of carbon that is added in to the air by burning natural gas can significantly affect the efforts to bring positive environment changes.

The results of burning natural gas

As we would keep on burning natural gas, little by little it would keep on adding more and more carbon to the air and which would result in greenhouse effect. By considering the damage that we have already caused on this dear planet of ours, we should take all the measures to repair the damage for our coming generations.

Finding Out The Solution

Natural gas is considered to be the safest fuel that does not pose much threat to the environment, the question is that even if we should avoid using it, what else should we opt for to meet our energy needs, the answer to this question lies in renewable energy resources. Instead of relying on the natural gas considering it as a safer fuel, the best thing is opt for fulfilling the energy needs by using solar energy and geothermal energy.

Renewable energy can help to resolve the problems such as increasing prices of fossil fuel oil, need for more energy for domestic use, and harmful air pollution. National renewable electricity standard can help to provide energy with clean domestic resources. That will help to stabilize electricity prices, reduction in natural gas prices, reduction of carbon dioxide emissions and other harmful air pollutants. Most of all it will create jobs especially in rural areas and farmers and ranchers will find new income.

What is a Renewable Electricity Standard?

The Renewable Electricity Standard (RES) or Renewable Portfolio Standard is a market-based process, which requires utilities to gradually increase the portion of electricity produced from renewable resources like wind, biomass, geothermal, and solar energy. Thirteen states including Texas had ordained minimum renewable energy requirements. But energy production makes national economic and environmental problems, which need national solutions.

The RES Relies on Market Forces

Use of tradable “renewable energy credits” for achieving compliance at the lowest cost, the functions like the Clean Air Act credit-trading system that permits lower-cost, market-based compliance with prescribed air pollution rule. This approach creates a competition between the renewable generators, providing greatest amount of clean power with lowest price and also plays major role for driving costs down.

Benefits of the Renewable Portfolio Standard

The Renewable Portfolio Standard is having following benefits:

Saves Consumers and Business Money

America’s homegrown renewable energy resources by several enterprises had created a more competitive market, which can reduce natural gas prices and save consumers money on their energy bills. Renewable energy is not responsible for changing prices that can harm natural gas power plants.

There are two recent studies, which made by the U.S. Energy Information Administration (EIA); they used high renewable energy cost estimates and find that a national RES will provide 10 percent of U.S. electricity from renewables till 2020 and that will lower natural gas prices. It will be having no impact o the electricity prices and will save energy consumers as much as $13.2 billion.

There is another 2002 UCS report “ Renewing Where We Live” also shows that a 10 percent by 2020 national RES will significantly reduce consumer energy bills. In this report this also had been looked that what will happen if the national RES were doubles to 20 percent by 2020. In this aspect , the RES will achieve greater diversity, economic development and also beneficial for the environment. And it will save $4.5 billion for consumer’s energy bills.

Reduce dependence on fossil fuels and lower fossil fuel prices

Studies by UCS, the Department of Energy, and other studies shows that RES is able to create healthy competition for fossil fuel power plants that are increasingly fueled by natural gas. When the natural gas heavy demand will reduce then RES will be able to reduce natural gas prices to homes and businesses.

Current chair of the Federal Energy Regulatory Commission and former Chair of the Texas Public Utilities Commission, Pat Wood who had implemented the nation’s most successful RPS to date says, “ The benefit of wind and solar energy is a predictable price path, and your variable costs will be zero.”

Foster economic development

This RES will arouse domestic investment in new renewable energy throughout the nation, creating jobs and income in rural areas and also in high tech and manufacturing sectors.

According to the U.S. Department of Energy Wind Energy would provide $1.2 billion in new income for farmers and rural landowners by 2020 and 80,000 new jobs. By tripling use of biomass energy in U.S. could provide as much as $20 billion new income for farmers and rural communities. When United States will be having a strong domestic renewable energy industry then the economy will benefit from the large export potential of this industry.

Reduce emissions and environmental impacts

Taking on a strong national renewable energy standard can reduce United States carbon dioxide emissions because the heat-trapping gas is first for being responsible of global warming from electricity generation. Along with energy efficiency improvements, power plant carbon emissions can be significantly reduced.

One of leading source for carbon emissions in U.S. is electricity generation. Almost 40 percent of carbon is emitted by power plants in United States.

A renewable energy standard will also significantly reduce other emissions such as nitrogen oxides, sulfur dioxide, and mercury. These mentioned pollutants mainly cause acid rain, smog, respiratory illness and water contamination.

EIA’s recent study shows that the RES could reduce the cost of controlling power plant emissions by reducing pressure on natural gas prices. RES will also reduce the need of drilling for natural gas, building new pipelines and power lines. It will also reduce the need for mining, transportation and burning of coal. Renewable energy can be more efficient and faster than developing new fossil and nuclear energy supplies.

When a brand new, a lot of needed, power generating facility is determined upon, several factors are taken into consideration. Pollution could be the primary and major consideration. Second to that, they conjointly address alternative considerations like placement, noise, appearance and economy of the facility.

These are valuable issues in the planning phases of such great projects and everybody is very snug with the actual fact that the authorities are committed to creating responsible choices for the short term and for the long term.

With the planet’s natural energy resources of the past and present, like coal and oil, nearing depletion together with the pollution factor for earth and also the atmosphere, they look into an alternate power source.

Too many times, they decide to make use of a nuclear power plant. Yes, it is a clean method for now but the pollution created when the usable energy is extracted from the radioactive materials used to power the system may be even worse than standard smoke and dirt pollution because the materials are still highly radioactive for lots of years to come. Our descendants may not love us too much for that call as a result of they can be burdened with the radioactive waste that we tend to created.

Many can say that nuclear energy use must be reduced or perhaps eliminated until somebody discovers a method to form these materials safe. If one thing major goes wrong with the nuclear waste, we have a tendency to could have pollution to the extend that earth could never get over it.

All this thought-about the obvious answer points to earth’s renewable energy resources. Not enough attention is paid to the present topic. There might be varied reasons why solar and wind energy publications lack exposure. One might be that the initial price of installations is too high. It may be because the sun and wind occurrence in some places are insufficient to make such systems work effectively. However, some places should be ideal for such installations.

One might say that the realm needed for a wind generating facility is many times larger than that required for an influence station, that is additionally true, but decentralization of the system can be implemented by placing wind generators on nearby mountaintops and different places where building or other development isn’t feasible. The following argument against decentralization may be the inconvenience with maintenance where some sacrifice might not be too expensive, all alternative edges considered.

If legislation, worldwide can be revised and “modernized”, small solar and wind combination systems can be put in at non-public homes with their surplus power feeding back into the ability grids, a giant amount of energy might be on the market for use while not having to run the ability stations on full power for a great deal of the day. This may take a massive portion off power production.

The best situation here would be that the home-owner makes the installation and for his value and maintenance on his system reduced power bills or no power bills at all or ultimately even payment from the ability company rewards him.

The argument against may be that homeowners have bonds to pay and have to work to earn enough with no time to spend maintaining their power generating systems.

Surely, there can be those who commit themselves to making a living off installing and maintaining power generating systems for others. Environmentalists and business opportunists alike ought to examine decentralized, renewable energy and contemplate the benefits for all together with the gain on ecological recovery.

There are various environment friendly and renewable energy resources available that offer alternate source of energy and help to nullify the effects of certain forms of pollution. All these power generation techniques can be described as renewable because they are not reducing the quantity of any resources to create the energy.

Here is a list of the top 10 renewable energy resources.

# 1 – Nuclear Power

Nuclear power is obtained through any nuclear technology designed to extract usable energy from atomic nuclei through controlled nuclear reactions. Currently,  only fission nuclear method is used, though other methods might one day include nuclear fusion and radioactive decay.

The reactors heat up the water to produce steam, which is then converted into mechanical work for the purpose of generating electricity or propulsion.

Fourteen percent of the world’s electricity is produced by nuclear energy. U.S. , France, and Japan together account for 56.5% of nuclear generated electricity.

439 nuclear power reactors are in operation around the world in 31 countries. According to the figures of World Nuclear Association during 1980s one new nuclear reactor starts up in every 17 days on average, and this ratio will increase till 2015 up to one reactor every 5 days.

France gets cleanest air than any other industrialized country because of nuclear power, and also cheapest electricity in all of Europe. For reducing mass and making more energy France reprocesses it nuclear waste.

By reprocessing, up to 95% of the remaining uranium and plutonium can be put into new mixed oxide fuel. Europe is considered to be the most successful re-processor but currently it only recycles 28% of the yearly fuel use, 7% in France and another 21% in Russia.

The energy experts believe that nuclear energy is a sustainable energy source that reduces carbon emissions and increases energy security by decreasing dependence on foreign oil. It is also emphasize that storing waste risks are low and using the latest technology in newer reactors can further reduce them. As compared to other major nuclear power plants the operational safety record in the Western World is excellent.

According to critics, nuclear power generation is dangerous even though using latest technology can lower the risks down. While on other side proponents advance the concept that nuclear power produces eventually no air pollution as compare to fossil oil energy producing and they also say that nuclear energy is the only virtual course to achieve energy independence for most Western countries.

But its being criticized also and critics say that radioactive waste can be contaminated by accident or sabotage as such accidents had happened before.

# 2 – Compressed Natural Gas (CNG)

Compressed Natural Gas is the substitute for the fossil fuel like gasoline, diesel or propane fuel. Though its combustion also produce the greenhouse gases but it’s more environment friendly as compare to other fossil fuels CNG is used in traditional gasoline engines which are converted into b-fuel vehicles (gasoline/CNG).

CNG vehicles are increasingly used in Europe and in North America. In Europe Italy is the no.1 and in world its 4th country with largest number of CNG-powered vehicles.

Canada is the largest producer of natural gas and CNG in Canada is used as economical motor fuel.

# 3 – Biomass

As a renewable energy source biomass refers to living and recently dead biological material that can be used as fuel or for industrial production. For that biomass make an appeal to plant matter grown to generate electricity or produce for instance trash like dead trees, yard clippings wood chip biofuel, and it also includes plant or animal matter used for production of fibers, chemicals or heat.

Industrial biomass can be grown up by several types of plants such as misconstrues, switch grass, hemp, poplar, corn sugarcane etc.

Biomass is a growing industry as demand for sustainable energy resources is increasing. Currently in U.S. 0.5% of electricity is produced by using biomass. New Hope Power Partnership is the largest biomass power plant in North America.

# 4 – Geothermal Power

The most efficient and powerful way to extract energy from earth through natural process is called geothermal energy. In ancient roman times it was used for space heating and bathing but now its better known to produce electricity.

Though geothermal power is cost effective, reliable and environment friendly but geographically its limited only to areas near tectonic plate boundaries.

The largest group of geothermal power plants is in the Geysers a geothermal field in California, United States. According to statistics 5 countries in world (EL Salvador, Kenya, Philippines, Iceland, and Costa Rica) generate more than 15% of their electricity through geothermal sources.

The main advantage of geothermal energy is that it doesn’t need any fuel. Geothermal electricity is generated in 24 countries around the world and still there are number of potential sites that needs any discovery.

# 5 – Radiant Energy

This natural energy is gained directly from environment or its extracted from ordinary electricity by using the fractionation method. Nikola Tesla invented the earliest wireless telephones based on radiant energy. This natural energy can work same as ordinary electricity at less than 1% of the cost. It doesn’t behave exactly like electricity.

# 6 – Hydroelectricity

Hydroelectricity is generated by hydropower. Using the force of falling or flowing water generates the power. This is the most widely used form of the renewable energy and it doesn’t produce any waste that will be harmful for the environment.

Hydropower produces the world’s almost 19% electricity.

# 7 – Wind Power

Conversion of wind energy by wind turbines into useful energy form such as electricity or mechanical energy is called Wind Power.

Wind power haves one the lowest environmental impacts of all energy resources. Recently wind produces only 1.5% of worldwide electricity but its growing fast. It achieved high level of penetration in many countries.

The wind power electricity production in few countries is phenomenal such as 19% of electricity production in Denmark, 11% in Spain and Portugal, and 7% in Germany and Ireland.

If we look in history humans are using wind energy from centuries such it was used to propel the sailing ships, for grinding grains and now today it is used to produce the electricity.

# 8 – Solar Power

Solar power is controls the suns energy to produce the electricity. This is one of the fastest growing energy sources and so many new technologies are developing with rapid speed to attain more from sun’s energy.

Solar cells are becoming more productive, flexible, transportable and easy in installation. Photovoltaic production was rise rapidly in 1973 due to of oil crisis.

Recent years solar installations are largely expanded to residential areas as governments are offering incentive programs to make green energy and more economically viable option.

# 9 – Wave Power

Transporting the energy from the ocean surface waves to capture the energy for useful work such as generating electricity, water desalination or pumping of the water is called wave energy.

This method of renewable energy is not most reliable due to unpredicted ocean and wave direction. Anyhow waveforms are in use in Europe. They are using floating Pelamis Wave Energy converters.

The world’s first commercial wave form is in Portugal, at the Agucadora Wave Park, that consists of three 750 KW Pelamis devices.

# 10 – Tidal Power

Tidal power generation is similar to a wind turbine power generation. It is more environment friendly and cause less impact on established ecosystems.

Tidal energy can be generated in two ways, one tidal stream generators and other by barrage generation.

Similar like wind turbines tidal stream generators rotate underwater swiftly driven by dense water.. Though its not used wider basis but its having a potential for future power generation.

Tidal energy production is more predictable than wind energy and solar power. Tidal mills were used in Europe and on the Atlantic coast of America long before.

Tidal power is directly derived from the motion of the Earth-Moon system, tidal forces are produced by the moon and sun with combination of earth’s rotation.

Lunar Energy Company in England had announced that they would build the world’s first tidal energy farm at the coast of Pembrokshire in Wales. It will be the world’s first deep-sea tidal energy farm, which will provide electricity to 5,000 homes.

Solar energy is electromagnetic radiation (including infrared, visible and ultraviolet light) released by thermonuclear reactions in the core of the sun. Solar energy transmitted to the earth in portions and it takes up to 9 minutes to reach the earth. Solar energy is the oldest energy source.

Water and land absorbed by solar energy. The half that makes it is absorbed by oceans, land masses and plants; in the ocean, the energy drives heat and wind-driven currents (like the gulf stream); on land, the energy is absorbed and creates heat, and the little bit that’s left is absorbed by plants and converted to chemical energy through a process we all know as photosynthesis.

Solar power is energy derived from the sun. Used synonymously with solar power, it is the ability of the sun to convert sunlight into electricity. What are the different types of solar power? Solar power can come in two main forms: Also known as solar heat energy, this is the sun’s ability to provide elevated levels of heat in the form of radiation.

Heat is one of the more sought after sources of energy in the market today. With solar power, air pollution reduced, as there are no fumes that are emitted while working with solar energy. Moreover, it is available free, where you only have to pay for the solar energy system, its installation, and wiring.

Solar power is the most democratic of renewable energy resources. It is available everywhere on the earth in quantities that vary only modestly. Only a very small percentage of the sun’s energy strikes the earth but that is still enough to provide all our energy needs. This is free to use as long as you have a system in place to capture it. Solar heat works by absorbing the sun’s radiation and converting this to heat energy. The concept of air movement, called natural convection, is an integral part of all successful solar heating installations.

If a heating system works with natural convection, hot air rising and cold air falling, then the result in comfort level can exceed expectations. Solar heating can be used to heat the space in your home or to heat the water in your plumbing system. There are many benefits to incorporating a solar heating system into your home’s design. Solar heat is environmentally friendly and does not pollute or produce greenhouse gases.

Solar energy is free, clean, and limitless and it is all yours. Solar solutions make it easy for you to enjoy year-round savings, protection from rising energy costs and boost your property’s value while helping protect the environment from pollution and reducing our nation’s dependence on foreign oil.

As it is known, the progress in material goods production is uniquely linked to the success of the energy base. By the middle of the 21st century, when the population of the globe apparently stabilize on a point of approximately 10 billion people, energy demand per capita will reach about 105 kW • h per year, and the power of the world’s energy supply – 1010 kW. Today, world energy system is mainly based on non-renewable energy resources such as coal, oil, gas, peat or uranium. However, it is clear that we will not be able to achieve a substantial increase in energy consumption based on these resources as their stocks are limited, and because of the adverse effects of these fuels on the environment. So scientists have turned their gazes to solar energy long time ago. Some projects involve different methods of solar energy transformation into electricity in space, distribution and delivery of it on Earth.

The efficiency of terrestrial solar energy conversion to electricity depends on their efficiency and the annual number of sunny days. 20 years ago the efficiency of silicon solar cells was equal to 15%. The efficiency of today’s GaAs element with three transitions is 34%, while promising devices with four conversions will probably be of 42% (theoretical value of the efficiency of four-element reaches approximately 50%). Today, 1 kg of solar panels provides 300 Watts. Capital cost for the panels of solar cells production has decreased from $ 50 to $ 5 / W in comparison to 80s, and the cost of energy consumption dropped from 0.9 to 0.2 $ / kW • h.

To overcome the dependence on weather conditions the project of creation of space solar plant located on the HIS, was advanced in the late 70′s, with the transfer of power to Earth using microwave radiation to Rectenna (that is antenna with built-in rectifier). The project was being elaborated on all components of the system, but has remained as just an interesting suggestion: although the station would be able to transfer 10 GW, which is equivalent to the output power of 10 nuclear power stations, the cost of the components raising on the satellite would have been $ 22 / g, and the mass of the satellite would have been 90 tons. Today, the picture changed. U.S. experts proposed major developments of such plants in the 35th Conference on Energy Conversion (IECEC) in July 2000.

According to these experts, new technology involving the use of high-performance solar cells, high-power semiconductor converters and magnetron generators, is capable to reduce the mass of the station significantly. Reusable transport aircraft invented by NASA, will reduce the cost of the components lifting into low Earth orbit to $2,2 / g (that is to say, in future it can reach 88 cents / g). Satellite solar power can be raised from low Earth orbit to geostationary one with the ion engine, fed by solar panels. The concept of an integrated symmetric concentrator (ISC) will reduce the mass of the controlling and power distribution system on the satellite, which constitutes a significant proportion of the mass of the whole station.
