采用超超临界技术，而美国只有0.76%。技术的差异使两国的排放水平也有所不同。此
外，中国的技术更为先进，机组的煤耗更低。每发1 kWh的电，中国的前100台机组平均
消耗286.42克标准煤（gce），而美国的水平是374.96 gce/kWh
在2020年前，中国现役燃煤发电机组的平均供电煤耗需要达到310 gce/kWh，目前美国
排名前100的机组都无法达到这一标准。 |

assuming T8's battery is on-par with other EV batteries, roughly 4miles/kWh,
then 25 AER translates into 6.25 kWh usable range out of the 9.2 kWh total
capacity (SoC=68%), then charging 6.25kWh with 12 hours on 110V is twice
slower than, for example, a volt (10 hours charging 11kWh out of 16.8kWh
capacity). This is similar with L2 charging.
unless the 9.2kWh number given by goVolvo was the usable range. |

1 therm = 100000 BTU = 29.3 kWh. 所以但从能量上你的natural gas是
~$0.02 / kWh. 电是$0.09 / kWh。所以电是天然气的4.5倍。但heat pump
的效率可以到400-450%, 所以理论上运行成本可能差不多。但如果heat pump
到不了450%，那就是天然气便宜。 |

打电话问pepco寻求建议 除了普通建议
指出我现在的electricity supplier是一个叫energy plus的公司 现在1 kwh=$0.169
pepco自己的rate 1 kwh=$0.093
赶紧给energy plus打电话 改成了 1kwh = $0.089 (fixed rate. will change back

如果冬天一个月用2000kwh 就差了$160
每个州不同的service area electricity rate也不一样

if it works, why not? it is a free feature coming with the car anyways.
it also works much better.
the power generator (range extender) in my 2014 volt can run 36-40 miles for
every gallon of gas. that is equivalent to the distance driven by 10 kWh
electricity from the battery.
With a 9.3 gallon gas tank, it can generate 93 kWh electricity, combined
with a drain-able 11kWh battery pack, that's a total of 104 kWh. That means
one tank can power 1500W appliances for 3 days at full load.

an average 2,500 sq. ft. single-family home uses about 5,000 Kwh of
electricity per year. A 3 Kwh solar system will generate nearly all the
electricity required for such a home on an annual basis.
A 3 Kwh Chinese solar panel system only requires 200 sq ft roof space.
For rooftop solar systems, space doesn't matter, you want to make the most
power for the least cost. |

1 L water = 1 kg
1 Gallon = 3.78 liter

The equation is E = m*C_p*delta_T, where E=heat energy, m=mass of water in
grams, C_p = 4.1813, and delta_T = change in temp in either K or degC.
To increase 1 gallon of water by 38C (typical hot water setting)
E = 4.1813 kJ/kgC x 1 kg/L x 3.78L/G x 38C x 0.000278 KWH/kJ = 0.167 KWH

同时，光伏发电首次超越了水电。
据德国能源与水经济协会（BDEW）的初步预计，2011年上半年可再生能源发电总量
达537亿千瓦时，相当于德国电力需求的20.8%。而2010年上半年，可再生能源发电总量为
504亿千瓦时，占电力总需求的18.3%。
像以前一样，风电成为发电最多的可再生能源，占能源总量的7.5%（2010年：6.6%
）。而光伏发电首次跃居第二名，为电网输送了3.5%的电力（2010年：2%）。同时，水
电排在第三位，占3.3%（2010年：3.6%）。
与去年一样，2011年上半年，以垃圾为燃料的发电厂以及其他可再生能源占发电总
量的0.8%

俺们这儿你选同一个电力公司的不同plan, regular 10.5c/kwh, clean energy 11.9c/
kwh, 其实流过你家的那些电子真的会有不同来源吗？ |

高速开的快的话,用油用电都会更费一点,40-42mpg或者略少于3.5mile/kwh.
如果把电池去掉,还可以省3-5%的油 |

长万钢透露，2009年-2015年，中国新能源汽车产量累计达到49.7万辆，这表明我国接
近完成《节能与新能源汽车产业发展规划（2012~2020年）》（以下简称“规划”）提
到的“到2012年时纯电动汽车和插电式混合动力汽车累计产销量力争达到50万辆”的阶
段性目标。
面对下一个“到2020年时产能达200万辆、累计产销量超过500万辆”的最终目标，
政策制定者虽倍感压力、但也是乐见其成。但关于我国将新能源汽车限定在“纯电动汽
车和插电式混合动力”以及由此制定的补贴政策争议不断，关于“纯电动汽车和插电式
混合动力”是否真能达到“节能减排”作用的争论却也是从未停息。
近日，日本汽车技术专家、马自达创驰蓝天技术之父人见光夫再次向电动汽车开
炮，“如果按照现在的发电方式进行计算，（从CO2减排的角度）电动汽车几乎没有意
义”。他通过长达50页PPT系统阐述了自己的观点，在现有的发电方法不改变的前提下
，将内燃机的实际油耗改善大约25%，CO2排放量就能达到与电动汽车相同水准。

发帖数: 1998 | 49 Thanks to nearby Niagara Falls, Plattsburgh has a quota of cheap
electricity available at a low rate - 2.7 cents/kwh for residential
or five cents/kwh for industrial use – against a US average of seven
or eight cents. The general rule of thumb for those wanting to compete
with Chinese miners is to keep electricity costs at four cents or less,
according to Shone Anstey, co-founder of Blockchain Intelligence Group.
And so Plattsburgh’s prices have attracted cryptominers to the region
since late 20... 阅读全帖 |

Today the average cost of energy from solar PV in U.S. is reported to be 12.
2 cents per kWh, which is about the same as the average retail rate. Those
who keep close tabs on electricity prices might think that it is about on
par with what they are paying for their own electricity at home.Mar 31, 2016
而化石燃料的发电成本是3.9 cent per kWh, 核能只有2.7
