The demand to fuel our industries has put a tremendous strain on the Earth's resources. As the world's population grows, so does our need for natural resources.
Coal, propane, natural gas, and fossil fuel resources are dwindling, and alternative energy sources are needed. We have options. Renewable energy means the supply will never run out, and solar thermal energy is the most abundant natural source available today. The more we adopt this form of energy, the sooner we can restore environmental balance.
