Energy Production Is As 'Dirty' As Ever
kkleiner writes "A recent report (PDF) from International Energy Agency delivers some dire news: despite 20 years of efforts toward clean energy and a decade of growth in renewable energy, energy production remains as 'dirty' as ever due to worldwide reliance on fossil fuels. With the global demand for energy expected to rise by 25 percent in the next 10 years, a renewed effort toward cleaner energy is desperately needed to avoid detrimental effects to the environment and public health. The report says, 'Coal technologies continue to dominate growth in power generation. This is a major reason why the amount of CO2 emitted for each unit of energy supplied has fallen by less than 1% since 1990. Thus the net impact on CO2 intensity of all changes in supply has been minimal. Coal-fired generation, which rose by an estimated 6% from 2010 to 2012, continues to grow faster than non-fossil energy sources on an absolute basis.'"
The article had one fact of which I was unaware, but should be entertaining:
"The boom in natural gas availability [mainly from fracking] pushed natural gas prices down last year to a 10-year low in the US. But the drop in US demand for coal sparked a drop in the price of coal, which in turn sparked a shift in Europe where coal replaced much of the more expensive gas to supply power stations."
"First they came for the slanderers and i said nothing."
The thing is, renewable energy is only uneconomical until it's not. Science and technology progress - pretending something won't ever work because it doesn't today is a dangerous line of thinking.
Progress comes in random spurts - but it always comes: http://www.digikey.com/Web%20Export/techzone/energy-harvesting/article-2011july-solar-cell2.jpg
