ABOUT RENEWABLE ENERGY
Renewable energy refers to energy that is generated from a renewable source, in other words a source that does not have a limited supply, like the sun, the wind, or water or any other source that does not pollute.
Our planet has a limited supply of fossil fuels, like petroleum, coal, and natural gas, and this supply will someday run out if we continue to use these traditional energy sources like we are today.
In addition to being non-renewable, fossil fuels emit harmful greenhouse gases into the environment.
Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization.
At this time there are no government subsidies in New Zealand but some power companies will buy power back from you into the mains grid.
According to a 2011 projection by the International Energy Agency, solar power generators may produce most of the world’s electricity within 50 years, dramatically reducing the emissions of greenhouse gases that harm the environment.
Renewable energy provides 18 percent of total electricity generation worldwide.
Some countries get most of their power from renewables, including Iceland and Paraguay (100 percent), Norway (98 percent), Brazil (86 percent), Austria (62 percent), New Zealand (65 percent), and Sweden (54 percent).
