1>A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions.
The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Globally, the average is closer to 4 tons. To have the best chance of avoiding a 2℃ rise in global temperatures, the average global carbon footprint per year needs to drop under 2 tons by 2050.
2>Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished. For example, sunlight or wind keep shining and blowing, even if their availability depends on time and weather.
3> It is considered an environmentally friendly source of energy because it comes directly from the Sun; it does not involve the burning of fossil fuels.
