Historically, wholesale power prices for Northern and Southern California tracked closely with one another, indicating minimal market differences between the two areas. However, after the shutdown of SONGS in early 2012, the relatively inexpensive nuclear generation produced by SONGS had to be replaced with power from more expensive sources. Consequently, since April 2012 Southern California power prices have persistently exceeded Northern California prices, with the spread averaging $4.15/MWh, or 12% of the Northern California price.
“PM2.5” seems an odd and wonky term for the blogosphere to take up, but that is precisely what has happened in China in recent weeks. It refers to the smallest solid particles in the atmosphere—those less than 2.5 microns across. Such dust can get deep into people’s lungs; far deeper than that rated as PM10. Yet until recently China’s authorities have revealed measurements only for PM10. When people realised this, an online revolt broke out.
New Hampshire, USA -- Japan this week marks the one year anniversary of the devastating earthquake and tsunami that has since forced it to re-evaluate its nuclear strategy. In doing so, it also unveiled a plan that could have big implications for renewable energy across the continent.
The UN estimates that 1.4 billion people have no access to electricity, hurting their ability to earn a living or educate their children. But connecting to an electric grid may not be the only solution.
Energy demands in South Asia are growing at rate of over 6.0 per cent a year - a pace that is far in excess of the region's capacity to meet. The fact that a sizeable section of the population does not have access to electricity makes energy security a daunting challenge for the countries of this region.
