the articles gives introduction to basic wind energy and wind turbine.

space based solar panels, its costs and benefits, and future ideas of solar panels in space

Renewable energy is quite useful in many ways. Reasons for renewable energy is that it is not dangerous in term of environment hazard. Renewable energy is very much friendly to earth and it keep the earth more clean and clear from pollution.

Solar energy is the best source to get the maximum benefit along with the clean environment. Solar energy creates no side effects that destroys the atmosphere of earth or boosts in global warming.

Passive solar energy is the use of solar power without involving the photovoltaic cells. There are plenty of methods to avail solar heat like solar oven and indoor heating techniques.

we need to save the energy by using alternatives and other manners to save the precious fossil fuels. For example we save electricity by turning off lights and appliances at homes when not in use.

Solar hot water panels is a great equipment to utilize solar heat in a different way. The solar hot water panels, as done traditionally performs best when they are placed at the rooftops and building roofs.

With no solution to stock energy, no number of solar panels can exempt a house from the electric grid. Scientists at Utah-based Ceramatec have built up an advanced battery that can be scaled up to stock 20-kW-hrs that is sufficient to power a norm house for almost one day. A simple sell for solar users, but it may also let the grid-bound to reserve power on less expensive on off-peak times.

the article mentions some of the guidelines regarding solar panels.

Randall Swisher, AWEA Executive DIrector, says that wind energy facilities are contributing 20% of the America’s electrical power provision by 2030 as visualized by the U.S. Department of Energy.

Energy projects for 2050 propose the earth will require between 28-35 terawatts (TW) per year, increasing from approximately 13TW in 2000. Nuclear will surely be an element but 8 TW of atomic power requires 8000 new powerhouses, or 1 fresh plant for each 1.4 days. Still the most hardcore advocates of the atom do not believe that is potential to occur.
