Last year we wrote an article on the uses of geothermal energy. Here is an updated version of that article with additional information. 1. Aquaculture and horticulture: Geothermal renewable energy is used in aquaculture, and horticulture, in order to raise plants and marine life that require a tropical environment. The steam and heat is all supplied by geothermal energy. 2. Industry and agriculture: Geothermal power generation is playing an increasing role in industry and agriculture. Timber is dried using heat acquired from geothermal energy, and paper mills use it for all stages of processing. The potential uses of geothermal energy in industry are huge. 3. Food Processing: The earth naturally contains an endless supply of heat and steam, which can be utilized to sterilize equipment and rooms. This would put an end to the use of chemicals for this purpose. There are many potential uses of geothermal energy in food processing, but as yet, this renewable energy source has yet to be utilized to a large degree in this sector. 4. Providing heat for residential use: Geothermal renewable energy has in the last few years caught the interest of an increasing number of house owners. Geothermal power generation provides more than just heat in summer; but a complete temperature control system which enables you to cool your home in winter as well. This significantly reduces heating and cooling bills, and keeps the home at a comfortable temperature year round. 5. Electricity generation: A geothermal power station works in a very different way to the geothermal power generation that would be used in the examples above. It provides not just heat and steam, but electricity itself. Geothermal power generation is completely clean, and releases no harmful gas emissions whatsoever. Many readers of this article will be most interested in single-home geothermal energy. As was explained, its use is limited to heating and cooling. However, indoor climate control can consume an enormous amount of energy in a big house, and by installing a geothermal heat pump this energy bill can be greatly reduced. Geothermal heat pumps move heat from below the ground into the home in winter and draw heat from your house into the ground in summer. Most geothermal energy pumps are simple and require little maintenance. They are not, however, a full-service solution. Some systems reduce energy bills by up to 40%, so you cannot get rid of your utility company straight away. One option is to install a small solar panel system to run the pump, and in doing so make you completely self dependant. A geothermal energy pump which can supply an average home’s needs costs around $8,000, however, the drilling and installation process cost in the region of $30,000.

There are more and more wind turbines appearing all around the world, so it was just a matter of time before a creation like the Wind Lens would make its debut. This type of wind turbine technology can bring the production of energy offshore. It also expands the reach of eco-power and can create much more efficient energy. The new creation made its debut in summer 2010 at the Yokohama renewable Energy International Exhibition.

Aquentium Inc (NASDAQ:ERII) announced last week that it has entered into a joint partnership with a Canadian company, and that together the companies will implement waste to energy projects across Canada. The company goal is to develop and implement new ways to recycle waste, which in turn generate electricity and reduce pollution in Canada.

The electricity demand on the East Coast this July 6th reached levels that have not been surpassed since the summer of 2006. Fortunately, the power grid held up well, for the most part. The fact that the East Coast did not have any major blackouts could be due to the billions of dollars that the power companies have spent over this past decade in order to prepare for higher demand. Despite this, many people still doubt that they have done enough. Most experts agree that there is much more to do, and that more upgrades will probably be required. This is good news for investors, as it creates a lot of investment opportunities for them.

Solar power should be able to to provide about 20 to 25% of global electricity by 2050, the International Energy Agency (IEA) says. 11% of the total power is predicted to be from home and office solar panels, and a further 11% will come from central solar power stations that will provide clean electricity for populous regions. A direct-current power transmission backbone would provide solar power to the whole country.

Many of us have been doing any research and are trying to go green by adding solar energy to either home and or office. This may be your first venture into the solar energy topic or like me, you may have been investigating it as a viable alternative for over twenty five years. While much has changed in the last few decades, there are some solar energy cons that you must take into consideration.

Quite a few European countries always seem to be ahead of the curve when it comes to instituting new ideas and technology. From Ireland’s PlasTax that adds twenty cents for each plastic bag used at the checkout to Norway’s electronic highway toll collection, Europe has been in the innovation lead for the best green approaches. This is never truer than using solar powered trees for efficient lighting.

Geothermal energy companies are America's future when it comes to energy sources. There are many advantages of geothermal energy. For one, geothermal renewable energy is good for the environment, as it is a good reliable energy source that is low-impact, and it is a cost effective source of energy. Geothermal energy companies are tapping into a quality, continuous source of energy that I believe will compose a lot of America's energy future. But first, what is geothermal energy? Geothermal energy is power that is extracted from heat from the earth. It is a renewable energy source that until recently was only able to be used from areas near tectonic plates, where high temperature energy sources are available relatively close to the surface. Recently however, geothermal energy companies have been able to utilize the Earth's heat away from tectonic plates. For example, there are several facilities in Europe that utilize geothermal renewable energy, such as one in Landau-Pfalz, Germany and Soultz-sous-Forets, France. A similar so-called demonstration project was shut down in Basel, Switzerland because it triggered a series of earthquakes, but it is not common for that to occur.

Do-it-yourselfers all over the country are turning their creative and innovative minds to the alternative energy industry by creating DIY wind energy power plants for use at home. Now, you may be asking yourself why and how would someone want to build a small wind power plant? The answer is that there are many wind energy advantages compared to traditional sources of energy, like oil and gas. Plus, it can be a lot of fun to build an actual working wind turbine at home.

As prices for solar equipment continue to slide, more affordable solar energy is now a reality. With that reality comes the exploitation of using this energy on a large scale to power entire communities and even cities. As technology continues to evolve, there are plans for a major solar thermal power plant to be built in southern California. California governor Arnold Schwarzenegger would like to see utility companies provide one-third of their output via solar power by 2020. This may be good news for people investing in solar energy stocks, but is the hefty goal safe for the environment?
