UNHCR spends US$35 million per year on diesel fuel to keep generators running. Solar will reduce cost, carbon emissions and other impacts.
Optimizing solar panels has long been a challenge for scientists and engineers. Solutions are on the way.
Many incentives can lower the cost of solar make it more competitive with other forms of energy generation.
Germany's economic growth has slowed significantly. Part of the reason is the country's flawed energy strategy.
Scientists estimated that 529,885 ha of PVs would be needed to replace the generation of all 2,603 hydro-dams in the US.
Energy derived from fossil fuels is far less efficient than previously thought, according to a new study.
