Four Main Sources Of Renewable Energy



With only a limited supply of oil and gas available on Earth, it is extremely important to find alternative sources of energy or else with the depletion of these natural resources, humans will be unable to fulfill a number of basic requirements.

4 sources

Renewable energy can be defined as any form of power that is derived from a source that cannot be depleted. Wind, solar, geothermal and tidal are examples of renewable energy.

There are several benefits of using renewable energy. It has some dominant environmental, economic and societal advantages. Renewable energy sources do not need any fossil fuels to generate power, which makes them environment friendly. Following are the main sources of renewable energy.

1. Wind

Wind energy commonly used to generate clean power, through the use of wind turbines that harness the power of offshore or land-based wind and convert it to electricity.

2. Solar

Solar energy can be utilized with the use of solar panels that allow us to use the enormous power of the sun to heat and lighten up our homes. Being made of photovoltaic cells, solar panels can easily be applied to roofs and even cars, to transfer sunlight to electricity.

3. Geothermal

The Earth’s core is the home to huge amount of heat. With geothermal power, the heat generated by the Earth can be used to by pulling it up to the surface using pumps.

4. Tidal

As the Earth comprised up to 70 percent of water, tidal energy presents a great source of renewable energy. Imagine the amount of power that many waves can produce. Tidal power uses the natural ebb and flow of the waves to generate electricity.

Wind Turbine Goes Portable



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. portable windturbine

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.

Learn The Disadvantages Of Solar Energy

Solar energy has been regarded as the solution to all our energy problems for the reason that the power we receive from the sun will never run out like that of fossil fuels, and it is also a free resource. Although there are many obvious advantages of solar energy, there are some disadvantages of solar energy to.

One of the major disadvantages of solar energy currently is the fact that there are insufficient solar technologies developed to fully provide for the energy needs of the globe’s inhabitants. There are some technologies like solar collectors that can help to provide some energy to your household. You can use this solar energy for your hot water systems and water heaters for your swimming pool. But these technologies are very inadequate in the amount of power that can be generated for your home. Many people get annoyed with this because they want to take advantage of using renewable energy, but don’t see the point of using this as it makes very little difference to your power bill and setting up such technologies takes so much effort.

One of the other major disadvantages of solar energy is the enormous cost involved with buying and installing the technology. You probably have heard claims before that solar energy is free energy and if you take advantage of such a resource you will never have to pay another cent to your electrical provider. This is not really true as the technology used to setup solar energy is usually just far too costly for many people to even consider such an energy option. Despite the fact that energy prices are expensive and the costs keep increasing, a lot of people are able to manage to pay a monthly electricity bill because the cost involved is predictable and controllable. However this is not the case with solar technologies as it can cost you up to $10,000 to install a solar powered hot water system that needs to be invested, and even then there is no guarantee that you will not have to pay for traditional electricity as well if the solar powered system does not work as satisfactory as you wish it to.

There are a few other disadvantages that prevent people from wanting to invest in such a technology. You may have come across that there is an vast amount of sunlight around us and so it will last forever, but what these theorists have failed to tell you is that the sun does not shine during the night and what are you going to do to get electricity then if you do not have the conventional types of electricity installed in your household. You still require energy at night to watch the television and make a cup of hot tea – and a number of the solar energy technologies do not take this into account. Before you go ahead to set up solar power systems you will have to take such things into consideration, if not you will be totally disappointed.

Solar energy appears too good to be true as it has been said that it uses the heat of the sun to power your house, and you will never have to pay another dollar on electricity. This is not true. There are a number of clear disadvantages of solar energy currently. To begin with the technology is a huge initial expense, the technology is not very matured yet, and the sun does not shine twenty-four hours everyday so you are not guaranteed to have power all the time. Take these into consideration before you look into powering your home with solar energy.

Dell Installs Solar Trees in HQ Parking Lot



The increasing depletion of natural resources has given way to new, innovative ways of using renewable energy.

This has caused the whole world to look up to industry leaders and other major corporations that can have a vital impact on the world’s power usage.

The good news is that Dell has stepped forward in order to fulfill its responsibility towards the society, and we can hopefully expect much more from the company in the future.

The Dell solar trees parking lot is one of the greatest ways to employ renewable energy. The Dell solar parking lot by Envision Solar, is an extremely unique way of using solar powered lights and it is something that is making immediate impact.

Not only the solar trees gather the suns energy as a viable energy source, but they even provides shade over about 50 parking spaces as well! The parking lot was designed in a way to make it viewable from the highway, so that Dell can let everyone know that solar power is the answer to the future needs.
