A Green New World
Renewable Energy is Powering the Future Renewable energy prices are rapidly declining and, in many instances, are now cheaper than oil, gas or coal. Private investment has surged into companies creating green technologies. These new technologies harnessing the infinite power of sunlight, wind, water and earth heat can produce considerable savings in terms of energy use and emissions, increased independence from fossil fuels and more jobs. Solar Solar energy uses sunlight and heat from the Sun as fuel for electricity production using various technologies. Two such approaches include photovoltaic (PV) devices which convert direct sunlight directly into electricity, and concentrated solar power (CSP) plants which focus sunlight onto central towers with mirrors to generate steam for turbines. Both industries have experienced rapid expansion, with costs dropping rapidly to become cost competitive in many markets. Scale economies and innovation are leading them toward becomin...
