Currently, the use of solar panels is on very small scale compared to the use of fossil fuels. This does not go for just solar energy, but also wind energy, geothermal, and tidal. The use of renewable electricity only makes up for a small percentage of a nations actual power output. There are however, some countries who are able to …

Active solar builds on the same principles as passive solar but uses additional technology such as fans and pumps to maximize the desirable effects and minimize the undesirable ones. It is used to produce energy for heating and cooling spaces, to store [tag]energy[/tag] for later use, and to heat water. Most active [tag]solar energy[/tag] systems use specialized collectors to capture the rays and used the stored power and additional electricity as necessary to run pumps and fans for distribution.

Every exposed part of a structure—walls, floors, windows, roofs—absorbs and stores or reflects away the heat radiated by the sun. Passive solar systems do this without any mechanical means (pumps or fans); they rely purely on design and positioning to work, which may include shutters or thermal curtains, dampers and vents, or other simple mechanisms.

the report shows that in 2010, renewable energy supplied an estimated 16% of global final energy consumption and delivered close to 20% of global electricity production. Renewable capacity now comprises about a quarter of total global power-generating capacity. Including large and small hydropower (an estimated 30 GW added in 2010), renewable energy accounted for approximately 50% of total added power-generating capacity in 2010. In 2010, existing solar water and space heating capacity increased by an estimated 25 gigawatts-thermal (GWth), or about 16%.
