Energy Diversification: A National Security Imperative
By WindPNews
and has no comments yet.
According to the Energy Information Administration, the U.S. imports about 60% of its oil, with more than two-thirds of it used for transportation. Oil is essential to the basic functioning of the global economy, from the production of goods in factories overseas and across the country to their delivery to local markets. Without oil our military would not be able to defend the country from external threats. In short, we are critically dependent on this non-renewable resource.

Global Wind Installations Boom, Up 31% in 2009
By WindPNews
and has no comments yet.
The Global Wind Energy Council this week announced that the world’s wind power capacity grew by 31% in 2009, adding 37.5 gigawatts (GW) to bring total installations up to 157.9 GW. A third of these additions were made in China, which experienced yet another year of over 100% growth. The main markets driving this significant growth continue to be Asia, North America and Europe, each of which installed more than 10 GW of new wind capacity in 2009.

Wind Turbines And The Surrounding Environment
By RenewableEnergy
and has no comments yet.
Although wind energy is a great source for renewable energy, there are many issues related to the impact of wind turbines on the surrounding environment, which contribute to the significant level of disadvantages of wind turbines.
In this article, I will discuss some of the impacts of wind turbines on the environment, and the disadvantages of producing electricity through wind turbines.
Noise Pollution
The most significant impact of a wind turbine on the environment is noise pollution. Although many people think that wind turbines are a great source of energy, a large proportion of these people would definitely oppose the development of a wind farm close to their home.
This is mainly due to the excessive noise, which is equivalent to that of a small jet engine. This noise pollution also lowers the property values within a varying radius of the construction area.
The noise pollution can greatly depend on the average annual wind speed (i.e. the higher the wind speed, the greater the noise output can be) and the size of the blades.
Visual Impact
Wind turbines can have a visual impact on the surrounding environment, which can be expressed with the term “visual pollution”.
Although some people feel that wind turbines actually look quite nice, many people disagree and think they spoil the landscape look.
Wildlife Impact
The third disadvantage of a wind turbine on the surrounding environment is its effects on the wildlife. Many a times, birds have been found dead around the base of turbines in wind farm areas.
You may be unaware of the force of the blades high up in the air, but they are more than capable of harming wildlife.
Although these impacts are significant, but newer technologies are being introduced to make wind turbines more environment friendly, and so we can expect to see many more wind farms constructed across the world in the near future.

Geothermal Heating and Cooling
By RenewableEnergy
and has no comments yet.
Many of us are unaware of the fact that geothermal energy can be used in the form of geothermal heating and cooling, helping you not only to maintain a heating system, but also to reverse the cycle and cool your home.
Although not all geothermal heat pump designs are designed to heat and cool your home, but you can request for the option.
Geothermal Heating
In order to heat our homes, we will have to extract the geothermal energy in some way, and the most common way is to use a ground source heat pump. It has now been several years since these technologies have been around, and we can see some proven results seen in Iceland, where this method has proved to be very efficient.
Geothermal energy can be used to provide energy to under floor heating systems in order to heat a building, or certain part of a building.
Geothermal Cooling
It is also possible to employ geothermal energy systems to reverse the process of heating, i.e. to the process of cooling. This can be understood as simply a reversal of the way the water flows.
In order to cool off our home, water which absorbs heat from our homes, is pumped through the pipes buried in the ground. This allows the water to cool off while the ground absorbs this heat energy. However, some external factors such as time of day also play an important part in this role, and additives may need to be placed in the water to do this.
Thus the process of geothermal heating and cooling is interlinked, and with some specialist, you can use this greatest renewable energy source to keep your house warm as well as cool without much expenditure.
