2. What are Solar Panels? Solar panels are devices that convert light into electricity. They are called "solar" panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Some scientists call them photovoltaics which means, basically, "light- electricity.“

3. What are Solar Panel Housing? Premium-quality Solar Home Solution systems with the most efficient photovoltaic (PV) solar panel modules in the nation, certified to UL standards and warranted for 25 years. Flexible financing options and one competitive project price that covers everything from your initial paperwork to the final cleanup.

4. Geothermal Heating Geothermal heating is the direct use of geothermal energy for heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the world, satisfying 0.07% of global primary energy consumption. Thermal efficiency is high since no energy conversion is needed, but capacity factors tend to be low (around 20%) since the heat is mostly needed in the winter. geothermal energyPJGW Thermal efficiencycapacity factors Geothermal energy originates from the heat retained within the Earth since the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. [2] Most high temperature geothermal heat is harvested in regions close to tectonic plate boundaries where volcanic activity rises close to the surface of the Earth. In these areas, ground and groundwater can be found with temperatures higher than the target temperature of the application. However, even cold ground contains heat, below 10' or 3 Meters, the ground is consistently 12.8°C (55°F) in moderate climates, and it may be extracted with a heat pump.

6. Reuse Construction Materials Recycling cuts energy consumption and pollution. Paper recycling can reduce air pollutants by 75% percent and water pollution by 67 percent; using scrap steel and iron rather than virgin products results in an 86 percent reduction in air pollution and a 76 percent reduction in water pollution; recycling aluminum saves 95 percent of the energy used to produce it from virgin products. A ton of recycled paper saves 17 trees and three cubic yards of landfill space. Buying recycled products is an essential part of making recycling work (closing the loop). The residential building industry can play a major role in helping to reduce waste and promote recycling by specifying and asking for recycled products
