      Note:  a LARGE power station =s 40 direct jobs.
  • workers at the large power station known as Keadby 1 are preparing to shut it down at the end of the summer, with the loss of about 40 jobs.
  • fluctuations in global energy markets have made the natural gas power plant unprofitable

  • It has also delayed new energy investments and is planning to close almost a quarter of its fossil fuel power plants,
  • European energy companies, struggling to respond to weak demand in a flatlining economy, say they need guaranteed pricing to keep open unprofitable plants or to invest in new ones.
  • Their revenue is being hit by dwindling demand for electricity and by new wind and solar projects that undercut the price of the energy produced from many fossil fuel plants.
  • At the same time, record-low prices on carbon emissions trading markets, which were introduced to encourage clean and efficient energy production and use, have perversely become a disincentive to investment.
  • Many of the Continent’s aging power stations, particularly those that burn highly polluting coal, are earmarked for closure by 2020 to meet stringent local environment regulations.
  • Without these investments, industrial companies in Europe may face higher energy prices when local economies eventually recover,
  • “Energy utilities are facing a perfect storm,”
  • In a bid to generate 20 percent of the European Union’s electricity from renewable sources by 2020, Germany, Spain and other E.U. countries have provided hefty subsidies to wind and solar farms, which now constitute a sizable minority of daily electricity generation, often surpassing the 20 percent target.

      In effect, a cheaper overall form of energy (non-renewables) had to compete with heavy subsidies to renewables, which, once built, had low operating costs.  They cannot compete and do not invest, and there are major problems w/investing more in renewables (they are overall more expensive, and they have built-in faults, producing electricity erratically, or during the wrong times.)  The high costs of energy also lie with government, who cemented long-term deals with the ex-USSR linking other energy prices to the price of oil.  In short, they shot themselves in the foot.  Several times.
  • Despite the upfront costs associated with green energy projects, they are inexpensive to run. In contrast, Europe’s gas and coal plants, which also provide backup power when renewables cannot operate, need constant spending on fossil fuels.
  • European utilities like E.On of Germany have announced plans to shut down less-polluting natural gas-fired plants that have been undercut by dirtier coal-burning generators benefiting from a flood of low-cost coal imports and low carbon emissions prices.
  • Policy makers are debating a system of support payments to keep uneconomic power plants open,
  • “Without long-term signals of energy prices, investment won’t happen.”
  • Some analysts also expect domestic regulators to eventually create financial incentives for companies

China exports pollution u s input_output

  • “We’re focusing on the trade impact,” said Mr. Lin, a professor in the department of atmospheric and oceanic sciences at Peking University’s School of Physics. “Trade changes the location of production and thus affects emissions.”
  • “Dust, ozone and carbon can accumulate in valleys and basins in California and other Western states,” the statement said.Black carbon is a particular problem because rain does not wash it out of the atmosphere, so it persists across long distances, the statement said. Black carbon is linked to asthma, cancer, emphysema, and heart and lung disease.
  • The study’s scientists also looked at the impact of China’s export industries on its own air quality. They estimated that in 2006, China’s exporting of goods to the United States was responsible for 7.4 percent of production-based Chinese emissions for sulfur dioxide, 5.7 percent for nitrogen oxides, 3.6 percent for black carbon and 4.6 percent for carbon monoxide.

  • The scholars who gave emissions estimates for China’s export industries, a significant part of the country’s economy, looked at data from 42 sectors that are direct or indirect contributors to emissions. They included steel and cement production, power generation and transportation. Coal-burning factories were the biggest sources of pollutants and greenhouse gases, which contribute to global warming.

  • In Japan, for instance, an environmental engineer has attributed a mysterious pestilence that is killing trees on Yakushima Island to pollutants from China.
  • Exports accounted for 24.1 percent of China’s entire economic output last year, down sharply from a peak of 35 percent in 2007, before the global financial crisis began to weaken overseas demand even as China’s domestic economy continued to grow.
  • But the proportion of China’s exports that are made in China has risen steadily in recent years as many companies move more of their supply chains, instead of just having final assembly work done here.
