Innovation Essential to Ensuring Future of Clean Energy
As the world races to transition away from fossil fuels, such as oil and natural gas, to renewable alternatives such as solar, innovation will be key to ensuring that the young green-energy industry has a future. Dozens of countries have already made significant progress in the transition, particularly in Europe, and the costs involved in building solar photovoltaic (PV) modules have dropped by more than 95% over the past several decades. Solar energy accounts for the majority of the world's green-energy capacity, followed by wind, thermal, hydropower and nuclear energy. While scientists are working hard to optimize solar technology and…
