We live in the renewable energy century. Solar and wind power are well-established technologies now, with continuously improving efficiencies, decreasing costs and rapidly growing market shares all over the world. Perceived green energy weaknesses are being addressed by ongoing improvements of, for example, the “smart grid� and energy storage options.
Above all, the renewable energy sector is permanently abuzz with exciting new developments. Here are just some of the innovations we can look forward to in the future:
High altitude wind power
The energy carried by wind streams at elevated levels in the earth’s troposphere has been estimated at over 850 terrawatts (TW) and represents an incredible potential resource, considering that humanity’s total annual energy budget amounts to “only� about 17 TW. Capturing some of this high-altitude wind power is not a new idea, but the technology to do so
