![]() You might think that the gasoline that makes your car run or the oil that heats your house are sources of energy that are not derived from the Sun, but in fact, the energy in gasoline and oil is really a form of stored solar energy, since the chemicals in gasoline and oil were created by plants, thousands of years ago, using the Sun as a source of energy. The energy stored in the food you eat can be traced back to the Sun, through the conversion of solar energy to chemical energy in the process of photosynthesis. Energy from the Sun warms the planet and keeps the global temperature within a range that allows life to flourish. From where does the energy around you come? Most of the processes that are critical for our day-to-day lives are driven by energy provided by the Sun.
