The chairman of Lightsource Renewable Energy said that renewable sources of energy offer a strong alternative to traditional "dirty fuels" such as coal.
"You cannot remove history overnight, but… I think today we have, fortunately, another solution in the energy basket," Vicente Lopez Ibor Mayor, chairman of Lightsource Renewable Energy, told CNBC.
"We have demonstrated year by year how (with) these solar industries and (the) renewable industry, we can provide solutions with strength, with consistency… and no doubt cleaner from the environmental point of view," he added.
Mayor's comments come on the same day that U.K. government statistics showed renewables' share of electricity generation rose to 25.1 percent in the first quarter of 2016, up from 22.8 percent in the first quarter of 2015.
By contrast, coal's share fell from 30.8 percent to a "record low" of just 15.8 percent, the government said.
