Smart Grid vs. Renewable Energy: Where Should We Invest? | Green Business | Reuters

‘Meeting energy needs while being efficient and using environmentally responsible technologies is probably the single greatest change that needs to happen to alter the effects of climate change now. In the United States and the European Union, governments are backing smart grid and renewable energy programs. Undoubtedly, the two technologies go hand-in-hand, but where should we put our efforts and dollars/euros first?’

Spaced Out: Is Solar Power From Satellites Achievable? – Environmental Capital – WSJ

This literally high tech approach is expensive and potentially politically dangerous. There is plenty of solar energy available for lower cost capture on the ground – is it reasonable to burn a lot of fossil fuels to get solar collectors into orbit so that we can beam additional energy down into an already overheated terrestrial system? Might this accelerate the development of space based military technology?

‘Space-based solar power is back in vogue these days, three decades after the U.S. government started toying with the idea as a way to get steady—if not cheap—power to remote battlefield locations. California utility PG&E just signed a deal with Solaren, another space-solar firm, to provide 200 megawatts of space-based solar power in 2016.’
