In the not too distant future, we don’t want to be looking our children in the eye and telling them:
“We had the chance, but we lacked the courage. We had the technology, but a narrow vision.”
Renewable energy, namely wind and solar energy, is a viable alternative to dirty and expensive energy such as coal. Küresel Enerji [D]evrimi raporu, (the Global Energy [R]evolution report) shows that renewable energy can meet the 38% of global energy demand by 2020 and 95% of it by 2050.
Renewable energy on the rise in developed countries
Renewable energy has improved incomparably in the last 25 years. Wind power is the most economical new power plant technology thanks to its low installation costs, lack of fuel cost, and a construction time of less than a year. Renewable energy can make significant contributions to the fight against climate change by reducing the use of fossil fuel. Turning to renewable energy can reduce the use of fossil fuel for electricity generation and heating by 90% by 2050.
Is there an example in the world?
Spain generated its electricity mainly from wind energy in the last quarter of 2012.
In 2010, China erected one wind turbine per hour.
In 2011, the use of wind power increased by 21% and its global market share increased by 6%.
Today 22 of the 75 countries that have built commercial wind farms exceeded 1 GW capacity level.
More than half of the wind power turbines installed in 2010 were installed outside the conventional markets of Europe and North America, and nearly all of them started to use wind power for the first time.
New Zeland sourced 10% of its electricity needs from geothermal energy.
Portugal’s renewable electricity generation capacity increased from 15% to 45% in a period of only 5 years.
