Renewable energy, led by solar power, could make up 80% of the growth in electricity generation over the next decade, according to a report. The International Energy Agency said it is now consistently cheaper to generate electricity by capturing the sun’s energy than by burning coal or natural gas in most countries. Solar photovoltaic cells are now one of the cheapest sources of electricity in history thanks to maturing technologies and policies that have reduced the cost of investments, the Paris-based agency said. Photovoltaic systems can be installed as panels on homes or businesses, as well as deployed at solar parks. The Agency sees solar becoming the new king of the world’s electricity markets.
