  While fossil fuels- coal,oil,gas- still generate roughly 85 percentof the

  world's energy supply,it'sclearer than ever that the future belongs to renewablesources such as wind and solar.The move to renewables is picking up momentumaround the world: They now account for more than half ofnew power sourcesgoing on line.

  Some growth stems from a commitment bygovernments and farsighted

  Businssesto fundcleanerenergy sources.But increasinglythestoryisabout theplummeting prices of renewables,especially wind and solar.The cost of solarpanels has dropped by 80 percent and the cost of wind turbines by close taone-third in the past eight years.

  In many parts of the world renewable energy is already a principal energy source.In Scotland,for example, wind turbines provide enough electricity to power 95 percent of homes. While the rest of the world takes the lead, notably China and Europe, the United States is also seeing a remarkable shift. In March,for the first time,wind and solar power accounted for more than 10 percent of the power generated in the US,reported the US Energy Information Administration.

  President Trump has underlined fossil fuels - especially coal - as the path to economic growth. In a recent speech in Iowa, he dismissed wind power as an unreliable energy source, But that message did not play well with many in Iowa,where wind turbines dot the fields and provide 36 percent of the state's electricity generation - and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.

  The question “what happens when the wind doesn't blow or the sun doesn'tshine?" has provided a quick put-down for skeptics. But a boost in the storage apacity of batteries is making their ability to keep power flowing around the clock more likely.

  The advance is driven in par by vehicle manufacturers, who are placing big bets on battery-powered electric vehicles. Although electric cars are still a rarity on roads now. this massive investment could change the picture rapidly in coming years.

  While there's a long way to go,the trend lines for renewables are spiking. The pace of change in energy sources appears to be speeding up perhaps: just in time to have a meaningful effect in slowing climate change.What Washington does-or doesn't do- to promote alternative energy may mean less and less a time of a global shift in thought.
