The total amount of solar energy reaching the Earth’s surface in tremendous and in order for us to replace carbon dioxide emitting sources we must first start by reducing our own energy demand. There are several ways of becoming energy-efficient such as better lighting, appliances, windows, and insulation. Synergy is a concept of renewable energy and energy efficiency and we see this illustrated in net-zero energy homes or buildings. (Turk and Bensel) Outside of our homes however, there is an entire world out there that has yet to catch up with the renewable energy revolution. Wind and sunlight are two forms of flow-limited energy, meaning, the wind is not always blowing and the sun is not always shining. To harness the immense amount of energy, I believe that CSP (Concentrating Solar Power) is the most beneficial resource currently available to limit our dependency on stock-limited resources such as oil and coal.
