A typical solar system will reduce the need for conventional water heating by about two-thirds. Often the plumbing from a solar heater connects to a houses existing water heater, which stays inactive as long as the water coming in is hot or hotter than the temperature setting on the indoor water heater. When it falls below this temperature, the homes water heater can kick in to make up the difference. Incorporating passive solar designs can reduce heating bills by as much as 50 percent. High-temperature solar water heaters can provide energy-efficient hot water and hot water heat for large commercial and industrial facilities.

Many large commercial buildings can use solar collectors to provide more than just hot water. Solar process heating systems can be used to heat these buildings. A solar ventilation system can be used in cold climates to preheat air as it enters a building. And the heat from a solar collector can even be used to provide energy for cooling a building. The Co-operative Insurance Building in Manchester has the largest commercial solar system in the UK. I think it looks very futuristic and cool!

You can generate electricity for a single building like more…

Once a distant technology that just sat on roofs that a few green minded people used, solar power has become a trendy tool we can hold in our hands. Sunlight - solar energy - can be used to generate electricity, provide hot water, and to heat, cool, and light buildings.Many large commercial buildings can use solar collectors to provide more than just hot water. Solar process heating systems can be used to heat these buildings. A solar ventilation system can be used in cold climates to preheat air as it enters a building.

Other recent outlandish additions include a solar-powered tent, scooter and LED house numbers, while mundane ones like bike lights, torches and radios have been around for years.

People can also use captured passive solar heat to cook food. A basic cooker consists of an insulated box with a glass top. Heat from more…
