Thousands of years ago, prosperous conditions in fertile river locations throughout the world motivated nomadic people to form sedentary, agrarian communities. The inhabitants of these areas built cities, learned to fabricate pottery and to use metals, invented writing systems, domesticated animals and created complex social structures. In short, civilization was born when hunters and gatherers became settlers and farmers.
Except for energy: today’s civilization is still based on gathering different forms of fossil energy, just like our ancestors, that collected berries and hunted animals until resources were depleted and they had to move elsewhere. Today, fossil energy resources are still sought and gathered until the last drop is spent. It becomes more and more evident that this is not a civilized behaviour, and certainly not a sustainable one, because there is no other planet in view to move to after resources are depleted and the atmosphere is spoiled.
However, our hunting and gathering ancestors found a solution to that dilemma: they became farmers, sowing seeds in springtime and harvesting corn and fruits in autumn, making use of technical know-how and the abundance of solar energy for their survival. That’s exactly what is overdue in the energy sector: we must become farmers for energy, sow wind farms, wave and hydropower stations, biomass- and geothermal co-generation plants, photovoltaic arrays, solar collectors and concentrating solar power plants and harvest energy for our demand.

SOLAR-THERMAL: CSP
CSP market set for 2011 solar boom. See this report from Lux Research: http://www.renewableenergyfocus.com/view/15617/csp-market-set-for-2011-solar-boom/
Solar dish-turbine systems generate electricity with low-water use due to compressed air technology, making it ideal for desert and other low-water locations.

LARGE-HYDRO: BIG – BIGGER – BIGGEST – BIGGESTER?
Brazil: 11,200-MW Belo Monte hydro project gets green light for construction.
The planned installed capacity of the dam complex would be 11,233 Megawatts (MW), which would make it the second-largest hydroelectric dam complex in Brazil and the world’s third-largest in installed capacity, behind Three Gorges Dam (China) and Itaipu Dam (Brazil-Paraguay): http://www.powergenworldwide.com/index/display/articledisplay/0544748059/articles/hrhrw/News-2/2011/01/11_200-mw-belo_monte.html
