Here is some excellent news about local action on the energy front. As you are reading this think about what might be done in your community.
The Power of Collective Energy Purchasing
JOHN FARRELL – Clean Technica
‘We can’t do it as an individual, But four hundred communities aggregating and asking for local wind power and solar power – that’s really powerful.”
Oak Park, IL, is one of hundreds of Illinois towns using their authority to buy electricity in bulk on behalf of its residential and small business customers. So far, most communities have used the policy – known as community choice aggregation – to negotiate for less expensive electricity compared to the default electric utility, Commonwealth Edison. Many have also purchased renewable energy credits with their power, but it’s not clear if the practice is greening or green-washing the power supply.
NASA Scientists Claim “Impossible” Space Travel Engine Could Actually Work
While some may say that nothing is impossible, that is a word that has been frequently used by experts to describe SPR Ltd’s EmDrive. To some, EmDrive is crazy, junk science that will never amount to anything; however, its inventor Roger Shawyer has stuck by it resolutely and insists that this novel spacecraft propulsion system works.
EmDrive is a highly efficient propellant-less propulsion system that converts microwave energy into thrust inside a sealed chamber. Such a system would be a complete game changer in spaceflight; it could dramatically cut the cost of satellites and space stations, extend the lives of spacecrafts and drive deep-space missions. But there’s a problem- it violates Newtonian laws of physics, in particular the law of conservation of momentum. Critics have therefore claimed that any thrust generated by prototype systems tested so far must be coming from another source.
‘There Will Be No Water’ by 2040? Researchers Urge Global Energy Paradigm Shift
Reports: World Faces ‘Insurmountable’ Water Shortage

Common Dreams, 30 July 2014
The world risks an “insurmountable” water crisis by 2040 without an immediate and significant overhaul of energy consumption and demand, a research team reported on Wednesday.
“There will be no water by 2040 if we keep doing what we’re doing today,” said Professor Benjamin Sovacool of Denmark’s Aarhus University, who co-authored two reports on the world’s rapidly decreasing sources of freshwater.
