  • Production of small SHP improves in the country
  •  
    "The installed capacity of small plants, called Small Hydropower Plans (SHP) increased almost three times between 2003 and 2010. In 2003, the power of these enterprises, each of which varies from 10 to 30 MW, totaled 1,151 MW, compared with 3,428.31 megawatts (MW) in 2010. The involvement of SHP in the energy matrix increased from 1.22% to 3.05% in the same period and the number of plants rose from 241 to 387 enterprises. Only in 2010, 32 small power plants came into operation, with total capacity of 470.67 MW. "

Small Wind Electric Systems: A U.S. Consumer's Guide - The Alternative Energy Store - 0 views

  • A very informative, quick-read guide on small wind systems is just a click away. This small reader is a great source of research if you would like to learn about wind and if it will work for you.

Small-scale wind energy | Carbon Trust - 0 views

  • Small-scale wind energy (wind turbines <50kW rated capacity) is receiving increasing interest as one of a number of microgeneration technologies with potential to reduce carbon emissions. Recent years have seen new products being made available on the UK market, which a survey by the British Wind Energy Association (BWEA) suggests is growing quickly.
    • Peter Fleming
       
      Yes, but I heard that the energy generation of wind turbines was proportional to the square of the diameter. Therefore if you just half the diameter of a large one you quarter the energy captured.
  • However, the overall potential of small-scale wind energy to reduce carbon emissions, and the conditions under which maximum carbon reductions can be made, have not been entirely clear.

Small Wind Test Findings - 0 views

  •  
    Small wind could cost 10 times the cost of residential solar to make the same power. The energy yield was measured in an average wind speed of 8.5 mph over the year. Here are the results, translated for the U.S. reader, with the comparative solar costs:

Appliances and Commercial Equipment Standards: Small Electric Motors - 0 views

  • The Energy Policy and Conservation Act (EPCA) of 1975 established an energy conservation program for major household appliances. The National Energy Conservation Policy Act of 1978 amended EPCA to add Part C of Title III, which established an energy conservation program for certain industrial equipment. The Energy Policy Act of 1992 (EPACT) also amended EPCA, and included amendments that expanded title III to include small electric motors. The Department of Energy, Office of Energy Efficiency and Renewable Energy, Building Technologies Program conducts the program that develops equipment energy conservation standards and has overall responsibility for rulemaking activities for small electric motors in fulfillment of the law.

Small wind turbine works at low wind speeds | Green Tech - CNET News - 0 views

  •  
    Homeowners this fall will be able to buy a wind turbine at hardware stores that tackles the small wind industry's bete noire: slow wind. WindTronics has developed a wind turbine sized for individual homes that it says can operate at speeds as low as 2 miles an hour. It will be sold for $4,500 as the Honeywell Wind Turbine... ... generate 2,000 kilowatt-hours in a year for a home with a very good--called Class 4--wind resource, according to the company. That's between 15 and 20 percent of the annual electricity consumption for the average U.S. home.

New funding for small business loans - 0 views

  • The Scottish Government’s small business loans scheme offers interest free loans of up to £100,000 to help save energy or install renewable energy technologies. Over 100 Small and Medium-sized Enterprises (SMEs) have already taken loans worth £2.5 million this financial year, the most in any one year since the scheme started in 2008, with estimated lifetime energy savings of 30,000 Megawatt hours.

DUJS Online » Motivating Energy Conservation Behavior without Monetary Incent... - 1 views

  • In theory, there are several basic economic and psychological motivators that motivate people to be more sustainable. It is easy assume that providing people with information that using less energy is more cost-effective would motivate a shift toward conservation. However, Fischlein observed that there is often an “energy-efficiency gap,” or a difference between what is economically efficient and what actually gets done. Fischlein stated that “more information alone is not enough,” as increasing awareness has been shown to increase knowledge while motivating little behavioral change.   According to Fischlein, even raising the price of energy might not promote a decrease in consumption because energy exhibits low price elasticity. She also observed “psychological licensing” related to energy use, which effectively means that people lose a sense of moral responsibility for their actions because they have to pay to consume. Motivating altruistic conservation is also difficult because energy use is not visible, so people cannot see the impact of their actions in any direct way.

How to Build a Small-Scale Hydroelectric Generator - 2 views

  • After we saw how to produce electricity using magnets or wind power, it is time to talk about those people who live near a river. In this case, the best way to produce electricity is represented by a small-scale hydroelectric generator made at home. Often called as a low-impact hydro, micro-hydro or run-of-stream hydro generator, this system is not very hard to build.

Making "Renewable" Viable: Drexel Engineers Develop New Technology for Grid-Level Elect... - 0 views

  •  
    "The team's research yielded a novel solution that combines the strengths of batteries and supercapacitors while also negating the scalability problem. The "electrochemical flow capacitor" (EFC) consists of an electrochemical cell connected to two external electrolyte reservoirs - a design similar to existing redox flow batteries which are used in electrical vehicles. This technology is unique because it uses small carbon particles suspended in the electrolyte liquid to create a slurry of particles that can carry an electric charge."

IBM, Harvard Launch Distributed-Computing Search for Super-Efficient Solar Cells - 0 views

  •  
    IBM and researchers from Harvard University launched a joint effort today to identify more efficient and lower-cost solar cell materials using distributed computing. Leveraging small amounts of computing power from potentially hundreds of thousands of personal computers, this latest addition to the company's World Community Grid platform will process more than 1 million configurations of atoms over the next two years in search of an organic molecule that can be used to make materials for an ultra-efficient plastic photovoltaic cell.

Missouri Town Powered Entirely by Wind - 0 views

  •  
    Missouri's a pretty tough place to grow most crops. But there's one thing they've got plenty of: wind. So a small town, Rock Port, has decided to use the powerful breezes to its advantage, building four wind turbines to provide power to their town.

    Aneel's College Board of Directors has authorized Copel (Paraná \nElectric Energy Company) to implement the pilot-project which determines the \nselling of exceeding energy, derived from animal waste, produced in small rural \nproprieties in Paraná. The project, named Distributed Generation with \nEnvironmental Sanitation Project, will allow the elimination of organic matter \nresulting from the hog creation, which will stop being released over rivers and \ndeposits such as Itaipu's. Such residue will be transformed, via biodigesters, \nin biogas, a fuel used in the generation of electric energy.

Consumers want energy use info, but don't want to pay - 1 views

  •  
    While most US residents say they're concerned about their home energy costs, only a small number are willing to pay upfront to gain access to real-time and detailed information about their energy consumption, according to a new survey released today by Oracle.
  •  
    I sympathise with these consumers. In Europe, I would guess the average utility bill not to be far from 200 euro per month, or 6-7 euro per day, and relatively stable. As a consumer, information on expenditure for food, transport and telecommunication might be as relevant, if not more.
