About The Show
The sun may be about 148 million kilometres from Earth but, for many people, it is perhaps the most accessible power source when they think of 'green' energy. Solar power enjoyed a surge during the 1970's energy crisis, but where is it in the age of global warming? Increased attention on renewables has refocused the spot light on solar power, but today's solar is more than just photovoltaic cells on roof tops. Explore the emerging world of Concentrated Solar Power (CSP), an evolving technology that harnesses the sun's rays on a massive scale to power entire communities. New CSP projects are thriving in hot spots like Nevada and Spain, where engineers race to tap this large-scale form of solar energy. But the technology is still dependent on one sometimes unpredictable factor: a sunny day. How will scientists meet the challenge of making solar more affordable and somehow storing its heat so this green energy can be relied upon anytime day or night come rain, hail or shine.
