Energy from the sun

Thomas Edison’s assertion that “genius is 1% inspiration, 99% perspiration” is particularly pertinent to the solar energy sector. This remarkable technology could hold answers to so many of the world’s energy challenges, but only at the cost of hard effort and investment. Solar Energy Perspectives, the first in-depth study dedicated to solar technology from the International Energy Agency (IEA), a sister organisation of the OECD, gives a comprehensive analysis of solar energy’s potential as well as the policies required to increase its capacity in the coming decades. Solar energy currently generates a tiny fraction of the world’s energy mix, paling even in comparison to established renewables such as biomass and hydro power, but the IEA predicts that up to 25% of global electricity could be produced by solar photovoltaic electricity (PV) and solar thermal electricity (STE) by 2050.
