Energy Efficient System for Desalination of Sea-water
: "Clean water is becoming scarce and until now the cost of desalination has been a barrier to exploiting seawater. However, a Danish company, HOH Water Supply (HOH), specialising in water technology, has overcome this barrier and invented a new method, which halves the energy consumption of desalination plants. The method, based on existing membrane technology, makes it possible to recycle 95% of the pressure used for pumping sea water through the membrane system. Thus the energy consumption at the desalination plant's pumps and operations are cut from about 7 kWh/m3 of water to 3-4 kWh/m3 of desalinated water. The new Energy Recovery System (ERS) has been developed by an independent engineer in co-operation with HOH. " 9:57:23 AM

Global Warming Gas Increasing Dramatically
: "Worldwide emissions of carbon dioxide are expected to increase by 3.5 billion tonnes, or 50 percent, annually by the year 2020, an executive for ExxonMobil Corp said on Wednesday. .. Experts say the United States, which has the world's largest economy and 4 percent of its population, is responsible for about 25 percent of so-called "greenhouse" gases now produced, but Broiles said most future growth in output will come from developing countries. "Eighty percent of that number, 80 percent of 3.5 billion tonnes, is going to be driven by those developing countries, those economies that are growing at the 4 to 5 percent range, so that's where it's coming from," he said.
A huge increase in the number of cars will cause part of the pollution growth. Broiles said there are now 15 cars for every 1,000 people in the world, but ExxonMobil expects that number to rise to 50 cars per 1,000 by 2020. He said ExxonMobil foresees a 40 percent increase in energy demand even though humans are boosting their energy efficiency by about 1 percent a year. Despite advances in technology most energy will still come from fossil fuels, and in particular oil and gas, of which there remain very large reserves, he said. " 9:03:16 PM
Spain to fund Mindanao solar power project
: "THE SPANISH government will invest 3.37 billion pesos in a solar electrification project that will light up 40 remote communities in Mindanao, Agrarian Reform Secretary Roberto Pagdanganan said. The Spanish government's Solar Power Technology Support (Spots) project is expected to benefit directly 20,000 farmers in 15 provinces in Mindanao, he said.
Pagdanganan said BP Solar España, which he described as the world's biggest solar plant manufacturer, had been contracted to provide technical services for the Spots project. " 8:34:30 PM

Solar in Tibet:"Since 1990, China has been promoting the "Sunshine Program" and the "Light of Science Program" in disadvantageous Ngari Prefecture to build solar power stations there. By now, about 60 solar power stations have been built and 80 percent of nomadic Tibetans are using solar energy for light and warmth at night. In a nomadic tent set up in Coqen county, 65-year-old Tibetan Dagyi said .. "My home can save approximately 100 ghee [yak butter for light] each year, which we can sell for about 1,200 yuan (about 145 US dollars)," said Dagyi. ..
According to sources with the Solar Energy Promotion Center in Ngari Prefecture, solar energy development has been introduced notonly for lighting but other areas like heating, agriculture, herding and use in water conservancy projects. By the end of the year, solar lights will be available for nearly 70,000 Tibetans in the prefecture." 8:31:03 PM

Renewable energy to light up 160 Mindanao villages: "Amore, a joint program of the United States Agency for International Development (USAid), Winrock International, Mirant Philippines in partnership with the Department of Energy (DOE) and the Autonomous Region in Muslim Mindanao (Armm), will ultimately electrify at least 160 barangays in several parts of Mindanao. .. Forms of renewable energy could include solar, wind, micro-hydro or biomass power. " 2:21:57 AM

Nigeria: Jigawa Earmarks N406m for Solar Power in 30 Villages
: "Jigawa government and a U.S.-based group, Solar Electricity Light Fund (SELF), have earmarked N406.69 million to provide solar energy in 30 villages in the next four years. The News Agency of Nigeria (NAN) reports that the solar energy project is designed to electrify community bore holes, health centres, primary schools and a mini-shopping centre in each village." 3:24:50 AM

BP Launches Rural Solar Project Initiative (October 28, 2003)
: "BP will lead an initiative with partner countries and financial bodies to structure a framework that simplifies the process by which funds are granted. The new framework for project terms would apply not just to solar PV but to any other form of renewable energy project for the developing world. The framework would standardize key areas such as the bid process, the evaluation criteria, the payment terms, maintenance, and performance criteria and remove anything that contributes to cost-adding unnecessary bureaucracy or, as importantly, does not support delivery.
Within the terms of this framework, BP will provide solar panels and services at cost over the next two years to developing world projects created under the auspices of the REEEP framework... the very fact that the business is approached as an intermittent series of projects increases costs because the start-up costs are repeated each time, and there are no economies of scale." The outcome of the proposed new framework is that it will help stimulate funds flow and efficient project administration and execution and contractors such as BP are held to account for delivery so that many more larger scale projects can be viable." 12:23:33 AM
