The United States government has passed various acts to legislate in the increasingly urgent field of energy. Over the last 20 years it has become apparent that humans are consuming energy at an unsustainable rate. The growing world population will only continue to consume at an even greater rate. It is a matter for governmental policy, and the US has tried to respond appropriately.
In 1992, the first major act to address the subject of climate change dramatically increased funding for alternative energy schemes.
The Stimulus package of 2009 , known variously as the recovery act, or ARRA, also contained several measures to invest in renewable energy and increase energy efficiency. A total of over $27billion was invested in alternative energy stimuli. The largest portion of this ($6billion) was designated for securing loans to install renewable energy sources. This made solar and wind energy much more achievable for millions of American citizens. Over $3billion was also set aside for carbon capture schemes, which aim to limit harmful emissions.
Although there is much more to do in this direction, many commentators argued that this showed a strong will to continue the fight against climate change, even in the face of a recession. Renewable energy can be economically beneficial, and this package made that clear.
