The document discusses renewable energy sources and determining the most reliable and efficient alternatives as current popular sources are being depleted. It notes that locations around the world require data collection and projects in New York and Germany have investigated reducing carbon dioxide emissions. Various researchers examined technical aspects of devices or their applicability by location, with most finding promising results except for aspects of New York's energy bill. The conclusion is that renewable energy is promising for most large countries, and failing to adopt such policies will lead to disastrous results in a short time.
