Wood Mackenzie, the electricity 'carbon neutral' or $4. 5 trillion dollars

Solar photovoltaic (pv) net news: wood Mackenzie reported recently, energy research institutions to fully transformed the grid for renewable energy power supply and will need to invest in the next 10 to 20 years. 5 trillion dollars, to achieve this & other; No & carbide throughout; Transformation.

, according to a report to completely get rid of the fossil energy, the grid needs to add about 1600 gigawatts of wind power and photovoltaic power, at the same time equipped with about 900 gigawatts of energy storage system. Wood Mackenzie, research director at the global wind energy Dan Shreve, points out that the extensive use of wind power and photovoltaic (pv) will need to be combined with large-scale energy storage investment, to ensure the stability of power grid.

in the meantime, Dan Shreve said: & other; To achieve 100% clean energy power supply has been well is not only the capital problem, need more radically redesigning the electric power market, from the original traditional architecture energy capacity into the market. ”

in addition, the agency said that if the United States will retain 20% of the existing natural gas power supply equipment, used for new renewable energy power supply cost will decrease about 20%, and the new energy storage cost will be reduced by about 60%.

solar photovoltaic network statement: this information is reproduced from the power grid cooperation media or other Internet website, solar photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. The article content is for reference only.

'photovoltaic (pv) of the world' this is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, wide-ranging, and can meet the needs of different readers. This paper not only includes editor Wolfgang & middot; Dr Parr, herself, in its new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and system summary, also include the global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development,

so, general literature in the list of solar power equipment cost, should be listed at the same time price of solar cells and solar power generation equipment prices. Do not agree now see literature. The authors believe is solar battery price for 3 in 2006. 15 $/ W, power generation equipment price $6 a/W, power generation cost is zero. $25 / kW· h。 Price of solar battery 1 in 2010. $8 a/W, price $3 / W power generation equipment, power generation cost is zero. $1 / kW· h。 Unfortunately, there is no clear refers to the average price of foreign or domestic, or the relationship between the power generation cost and the feed-in tariff, so only a feed-in tariff 3. 4 yuan or 4. 5 yuan/kW· H and power generation cost is zero. $25 / kW· There is a big gap between h, let the reader can't figure out what is going on? According to references [ 1] Provided in the wind power cost and price of relationship, can be calculated: a feed-in tariff is equal to the cost by 120% ( Consider 20% profit) Take the 117% ( Consider 17% VAT) , that is, a feed-in tariff is equal to 1. 404 times the cost. According to this algorithm, a feed-in tariff for solar power generation equipment in 2006 ( The yuan) 2. 8 yuan/kW· H, around 2010 a feed-in tariff should be 1. 12 yuan/kW· H ( $1 of 8 RMB yuan) 。
