Renewable energy systems are rapidly becoming more efficient and cheaper. As of 2015 more than 50% of new electricity capacity installed worldwide are renewable. Renewable resources include sunlight, wind, rain, tides, waves, and geothermal heat, with solar photovoltaics being the largest renewable employer globally. While many renewable energy projects are large-scale, renewables are suited to remote areas and developing countries.
