"Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture."
The use of photovoltaic cells to convert sunlight into electrical energy.
"Its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power."
"Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy."
"Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air."
"The development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries' energy security through reliance on an indigenous, inexhaustible, and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating global warming.... these advantages are global."

"Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy."
"It is an essential source of renewable energy."
"In 2011, the International Energy Agency said that 'the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits.'"
"These advantages are global."
"Reliance on an indigenous, inexhaustible, and mostly import-independent resource."
