When trying to be positive when speaking about climate change, politicians speak about "green" energy production. Solar and wind power are the two most broadly deployed "green" power production technologies. Wind power has been around for several hundred years, has severe limitations imposed by the laws of physics (at most turbines can only capture 59.3% of the energy of the wind, a property know as Betz' Law), and has profound detrimental effects on the environment itself. These environmental effects include deaths of huge numbers of migratory birds (including many different eagle species) to noise pollution to ruination of the natural beauty of land and sky. Solar is far more promising, and has not yet reached anywhere near maximal theoretical efficiency with photovoltaic cells. However, both of these options remain far too expensive to be used on a large scale, especially in developing countries where the cheapest option for electricity generation is almost always coal (which produces the most carbon emissions).
Rather than fretting over increasing carbon and possible global warming, rather than waiting for politicians to act, be part of the solution. Start planting trees on a large scale with the Groasis Waterboxx, either on your land or with a local city beautification (tree planting) group.
