Sunday, July 29th, 2007 Even a few days of unexpectedly hot weather, given the soaring costs of energy, can send even the best-planned home energy budget into a tailspin. Homes with air conditioning units have barely livable interiors, and those without them are simply unlivable. But there is a bit of hope, in the solar powered attic fan.
Attics, […]
Green energy
Friday, July 27th, 2007Green energy includes natural energetic processes that can be harnessed with little pollution. Anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar power, biomass power, tidal power and wave power fall under such a category. Some versions may also include power derived from the incineration of waste.
More controversial is nuclear energy’s claim to be green. […]
Solar heating systems
Monday, July 23rd, 2007Solar hot water systems use sunlight to heat water. Solar hot water systems were used extensively in the United States up to the 1920s until replaced by relatively cheap and more reliable conventional heating fuels. The economic advantage of conventional heating fuels has varied over time resulting in periodic interest in solar hot water; however, […]
Solar Panels Creativity
Saturday, July 21st, 2007Think about all the things that use energy; practically anything: cars, boats, factories, planes, ships, helicopters, and of course homes: air heating, water pumps, wall outlets, stoves, fridges, computers, etc.
Imagine of most of these things using solar power — great, eh? In a few year’s time, solar powered cars would be quite possible. Even […]
Solar Panels and their Foults
Wednesday, July 18th, 2007All that black stuff you find on solar panels is called photovaltaics. It is the most important part of solar panels - the part that makes electricity. You might have heard that solar panels don’t last for ever. That is so true… but if your panel is not taken good care of; it might not […]
Solar Panels Hot Water
Tuesday, July 17th, 2007A solar hot water panel is a solar water heater that uses the sun’s energy to heat a fluid, which is used to transfer the heat to a heat storage vessel. In the home, for example, potable water would be heated and then stored in a hot water tank. Flat-plate solar-thermal collectors are usually placed […]
Solar Panels
Friday, July 13th, 2007These days, solar panels are pretty practical, especially for remote homes. Until solar power came along, people who wanted to live in remote areas frequently had to pay large fees to have a power cable run to their house. Now, a remote home can be virtually self-sufficient with solar power. Even in areas where power […]

Solar Panels Cars
Wednesday, July 11th, 2007With the solar panels stuff, people have tried to make energy efficient transport. Well, it’s no fairy tale of course… The solar-cars idea has worked. Nowdays people compete in solar powered cars competitions. The so-fa car so far is the fastest ( Don’t mix it up with sofa!) in the solar powered car competitions. Most […]
Solar Panels Attic Fans
Monday, July 9th, 2007Q: My attic space gets as hot as blue blazes. I saw an advertisement for a solar-powered attic fan and that seems like a great way to remove heat and reduce my carbon footprint. Do these fans really work, and are they hard to install? Will the fan significantly reduce the temperature […]
