It uses mechanical tools and equipment like fans, pumps and blowers to help people gather, store and distribute the heat all over the home. The systems can be air-based or liquid-based. Liquid-based systems involve the use of large water tanks or thermal mass for the storage of heat. Distribution is managed through radiant slab systems, hot-water baseboards and central forced air systems. Practical Use The first commercial electro-solar hybrid car, called the Venturi Astrolab was introduced in 2006. Some companies in May 2007 also worked to change a Toyota Prius to utilize solar cells to create up to 240 watts of electrical power under the sun. Golf carts are shown to have very practical uses if powered by solar energy. Solar radiation, together with secondary solar-powered resources like biomass, wind, wave and hydroelectricity are accountable for majority of the available renewable energy on Earth. Only a small fraction of the available solar energy is utilized. Solar powered electrical generation depends on photovoltaics and heat engines. You need to use the right type and size of windows to reduce the heat during extra hot days. Landscaping and structural features can be used to make shade. The home also has to be insulated well to keep the right temperature. On Daylighting Daylighting is a kind of solar energy lighting. It is described as the use of natural light to illuminate the house. The photovoltaic effect is achieved when light is converted into electricity. You can then have direct current electricity. When the power enters an inverter, you can get 120 volt AC conversion, the same electricity required to power the house. The connection will be to the utility panel so that appliances and lights will work the same way when the switch is turned on. Compared to oil, oil burning will release carbon dioxide plus other greenhouse gases into the air. The process of getting oil can also lead to damaged or compromised ecosystems because of spills and dredging. Cheap and Easy People do not have to keep maintaining solar cells, because a panel can last about 30 years or more if well kept.
