Harnessing Earth's energy one day at a time. Harvesting Earth's energy one season at a time. Life on earth is sustained by the light and heat of the sun.

Geothermal Energy

What Is Geothermal Energy? Geothermal energy is the natural heat of the Earth, which is transferred from the hot core of the planet to the much cooler surface by conduction of heat through rocks. It is this same heat that produces the molten lava, hot ash and gases that we see spewing from an erupting volcano. Geothermal energy can be harnessed by modern technology and brought to the surface as steam or hot water and converted to electricity.

Ocean Energy

Oceans cover more than 70% of Earth's surface, making them the world's largest solar collectors. The sun's heat warms the surface water a lot more than the deep ocean water, and this temperature difference creates thermal energy. Just a small portion of the heat trapped in the ocean could power the world. Oceans also produce mechanical energy from the tides and waves. Even though the sun affects all ocean activity, the gravitational pull of the moon primarily drives the tides, and the wind powers the ocean waves. — Exploring Ways to Use Ocean Energy

Why Energy Storage?

One of the greatest challenges facing the electric power industry worldwide is how to harness the immense renewable energy resources and deliver them in a useable form as a higher-value product. By storing the power produced from renewable sources off-peak and releasing it during on-peak periods, energy storage can transform this low-value, unscheduled power into schedulable, high-value 'green' products. Developing these resources will not only lessen environmental impacts but also increase each country's domestic energy security (lowering payments for imported energy).

Water

The world is not running out of water. A shortage of inexpensive clean water has become a problem in some areas because population growth has caused the demand for fresh water to increase to the point where lifestyle changes and government intervention are needed to prevent crisis. Drought is a regional problem, and one that can be solved through technology and civil engineering.
