-- a _kt75 | reprint Download: Quarterly Notes on Sustainable Water Management - Q01/2014 The energy economics of the world is now at a crossroads, giving rise to a fiery debate among experts whether it will bring about a momentous change in the world’s strategic balance. The Ukraine crisis has given an impetus to it by threatening a cut in the supply of Russian oil and gas to Europe; the West is now on the lookout for an alternative source of energy. With the United States making rapid progress in the area of shale oil and gas technology, and several large-scale shale reserves being discovered in Western Europe and Latin America, dependence on hydrocarbon supplies from the Middle East and the Persian Gulf will decrease, which will ultimately lead to a lapse in big power involvement in the region. This has all come as a boon to American companies involved in the exploitation of shale resources, and they are leaving no stone unturned in sweeping away the impediment...

-- a _kt75 | reprint Download: Quarterly Notes on Sustainable Water Management - Q01/2014 In 2012, coal-fired and nuclear power plants together provided 56% of the electricity generated in the United States. The role of these technologies in the U.S. generation mix has been changing since 2009, as both low natural gas prices and slower growth of electricity demand have altered their competitiveness relative to other fuels. Many coal-fired plants also must comply with requirements of the Mercury and Air Toxics Standards (MATS) and other environmental regulations. Some of the challenges faced by coal-fired and nuclear generators, and the implications for electricity markets if the plants are retired in significant numbers, are analyzed in this discussion. Of the total installed 310 gigawatts (GW) of coal-fired generating capacity available at the end of 2012, 50 GW, or 16%, is projected to be retired by 2020 in the AEO2014 Reference case. Despite those projec...

The worldwide demand for solar and wind power continues to skyrocket. Since 2009, global solar photovoltaic installations have increased about 40 percent a year on average, and the installed capacity of wind turbines has doubled. The dramatic growth of the wind and solar industries has led utilities to begin testing large-scale technologies capable of storing surplus clean electricity and delivering it on demand when sunlight and wind are in short supply. Now a team of Stanford researchers has looked at the "energetic cost" of manufacturing batteries and other storage technologies for the electrical grid. At issue ...

-- a _kt75 | reprint Download: Quarterly Notes on Sustainable Water Management - Q01/2014 When Ergon Energy began a Solar Cities program on Magnetic Island to try to make the isolated community as efficient and self sustaining as possible – and avoid an expensive new cable to the mainland grid – one of the first things it did was to remove all the old bar fridges. It filled up more than a shipping container and took them off the island. Bar fridges, explains Ergon Energy CEO Ian McLeod, are usually old, and terribly inefficient. Roofs on the island were also painted white to dissipate the effects of the sun’s heat on household interiors. Solar was installed and the new cable deferred for nearly a decade. Now, with storage about to be installed on Magnetic Island, the new cable will probably never be needed. This is now becoming the model for regional and isolated communities around Australia . Inefficient appliances like old bar fridges are being replaced, local gene...
