Falling costs and rising concern about climate change are fueling a global boom in renewable energy.
Renewables now account for approximately 50% of global new electricity capacity. Wind, solar, hydro, and biomass are cumulatively providing more than 100,000 megawatts of new capacity per year.
While renewable energy is already a big business around the world, the best days for renewables are ahead. Why? Costs of renewables continue to decline and temperatures and seas continue to rise.
