What is essential for energy?

Answer 1

From the very dawn of life, energy has been required to sustain life. The Sun has provided the heat and light that fuels all of the complex chemical reactions life requires.

Plants use light from the Sun to create sugar and oxygen. These plants in turn provide food and oxygen for animals.

Energy from the Sun drives the wind and ocean currents that power ships, wind mills and wind generators.

Energy has been required by life since life began. As we progress technologically, our energy needs increase. An ever growing population has used oil, coal, and other resources past the point of sustainability.

The sustainability of energy and life here on Earth is forever linked to the Sun.
