Global renewable energy sector to grow
More solar power and wind power installations are likely to be built over the coming years as investment levels in the renewable energy sector increase over the next decade, a United Nations report has said.
Investment in global renewable energy is likely to increase from $1.4 trillion in 2010 to $5.1tn in 2020, the report said. This, combined with the reduced cost of solar installations, wind turbines and other such technologies, is likely to see the number of environmentally friendly building projects rise in the near future.

Wishful thinking because
Solar and Wind are not renewable. The energy from solar and from wind is of course renewable but the devices used to capture the energy of the sun and wind is not renewable. Nor are they green or sustainable.
An oak tree is renewable. A horse is renewable. They reproduce themselves. The human-made equipment used to capture solar energy or wind energy is not renewable. There is considerable fossil fuel energy embedded in this equipment. The many components used in devices to capture solar energy, wind energy, tidal energy and biomass energy – aluminum, glass, copper, rare metals, petroleum in many forms to name a few – are fossil fuel dependent.

Oil, coal and nuclear are increasing in cost. Wind and solar are dropping in price as research and development ramp up and economies of scale take place. The transition has begun.
