发帖数: 901 | 1 Coal today is largely a story about electricity use… And the world consumes
staggering amounts of power. Electricity is a fundamental fact of modern
life. It powers virtually everything we do – from heating the stoves that
cook our dinner and lighting up the TVs we watch, to powering the massive
factories that build cars and refine natural resources.
And as countries like China and India (aka "Chindia") modernize their
economies, the volume of electricity they devour is mind-boggling.

感觉良好的ZENN公司与宣称拥有超级电容技术的EEStor公司，通过技术建立合作，
试图打造出一个能够改变世界的产品，但困难重重。
2009年9月，加拿大电动车制造商ZENN宣布放弃之前的战略，不再量产可以在高速
公路上行驶的纯电动汽车。而去年此时，他们正与加拿大政府对簿公堂，为这类电动车
争取上高速公路的权利。
这是ZENN创办以来战略调整最大的一次。ZENN公司创办者、CEO安·克利福德
（Ian Clifford）说："2008年，电动汽车产业发生了巨大的变化，我觉得我们的业务
模式不应该局限于销售和生产电动车。"新计划是，未来ZENN不再进行电动车量产的开

多伦多能源调查机构(Energy Probe)前总裁暨咨询师亚当斯(Tom Adams)说：「民众遭到劫掠，会感觉到痛楚。民众每年要多掏腰包，我对此愤怒，民众也是一样。」
由于安河能源署(Ontario Energy Board)今年5月1日批准了渥太华电力局(Hydro Ottawa)调涨电价的申请，以及今年7月1月实施的安河两税合并(HST)，渥太华民众的今年电价呈两位数增长，以典型的渥太华每户每月用电量800度(kilowatt hours)为例，现在没有含税要支付116.82元，比今年4月份的每户每月99.35元上涨了17.7%，涨价部分一半源于电价上涨，另一半则源于两税合并。
亚当斯提醒说，安河民众在2011年底时会发现自己每年至少要多支付110元电费，换言之，电费要额外上涨9%。
按照他的预测，在2011年往后，电价还要再上涨4%至5%。
