Solar Energy Net Metering Net metering is actually a means for people who use solar energy to power up their homes or work place to be able to sell back to the utility company whatever excess electricity that their home or work place is able to produce using solar energy technology, but is not able to use up. Heat Movement Assessment It is important that people know more about the movement of heat to full appreciate solar thermal energy. Passive solar energy applications use a lot of heat movement. The 3 common physical ways that heat moves include convection, conduction and radiation. Conduction is the transfer of heat via a solid material, or from a single material to another where the surfaces are in contact with each other. There are several applications that you can try depending on your setup. Here are some tips. The Advantages Active solar energy can provide people with many benefits. It can be used on your present home regardless of the current design or orientation. Active solar energy can produce a lot more solar thermal energy compared to passive solar energy. This is probably the main reason as to why the people during those times, especially in native South and North America, as well as in other parts of the world, worshipped the Sun. Ancient Greece built temples devoted to worshipping their sun deities, namely, Helio and Apollo. Also, the Greek s use of solar energy were not limited to religious purposes, as they even used the solar energy system to incorporate passive solar design in the construction of their houses. You can let your kids go to different areas of the house without having to worry about pollution and poisoning. Getting a system also means that you are saving the surroundings from stress and other pollutants in the years to come. You can get a cooler and cleaner environment by investing in a solar power system. Another problem that solar energy systems would encounter would be the integration and retro-fitting of these solar energy systems to the different houses and structures that are already constructed without any solar energy system incorporated in them. Solar Energy in the Future The future of solar energy appears to be gearing towards the better, especially since there are a lot of research and developments that are being done by different researchers and scientists, all focused on finding ways to improve alternative energy systems and technology.
