Solar and Wave Power

A friend of mine forwarded me a couple of insightful articles into the solar industry, as well as tidal power which isn’t talked about all that much.  I thought it would be could to plug both the solar article in National Geographic, and the wave article in the Smithsonian Magazine.  Here’s two excerpts, one from each article.

Solar:  “With a new administration in Washington promising to take on global warming and loosen the grip of foreign oil, solar energy finally may be coming of age. Last year oil prices spiked to more than $140 a barrel before plunging along with the economy—a reminder of the dangers of tying the future to something as unpredictable as oil. Washington, confronting the worst recession since the 1930s, is underwriting massive projects to overhaul the country’s infrastructure, including its energy supply. In his inaugural address President Barack Obama promised to “harness the sun and the winds and the soil to fuel our cars and run our factories.” His 2010 budget called for doubling the country’s renewable energy capacity in three years. Wind turbines and biofuels will be important contributors. But no form of energy is more abundant than the sun.”

Tidal: ”  As the sun set, it hit me: I could ride waves all day and all night, all year long,” says von Jouanne. “Wave power is always there. It never stops. I began thinking that there’s got to be a way to harness all the energy of an ocean swell, in a practical and efficient way, in a responsible way.”

Today, von Jouanne is one of the driving forces in the fast-growing field of wave energy—as well as its leading proponent. She will explain to anyone who will listen that unlike wind and solar power, wave energy is always available. Even when the ocean seems calm, swells are moving water up and down sufficiently to generate electricity. And an apparatus to generate kilowatts of power from a wave can be much smaller than what’s needed to harness kilowatts from wind or sunshine because water is dense and the energy it imparts is concentrated.
