The Oil Drum | Has Fossil Fuel Consumption Within the EU Peaked? - 0 views

  •  
    As this post will show the likelihood that the EU's fossil fuel consumption has peaked, back in 1979, is now very real. It will also compare the degree of net fossil fuel self-sufficiency between the EU and the USA as of 2007.

Green roofs reduce energy consumption - 0 views

    Green roofs - where traditional roofs are replaced with plants and a watering system - optimise the energy consumption of buildings and have other advantages, say Spanish researchers.

Improving efficiency of US homes could cut energy consumption 22.5% - 1 views

  • If all US homes built before 2000 were brought up to the same efficiency standards as those built after that time, energy consumption would fall 22.5%, according to a new report.The study by the Joint Center for Housing Studies of Harvard University, which was co-sponsored by the US Green Building Council (USGBC), looked at the affordability, energy and location efficiency of the country’s existing housing stock.

Efficiency key to making Denmark fossil fuel-free by 2050, says report - 0 views

  • In this ‘green’ future, electricity will comprise 40-70% of energy consumption, up from around 20% now. And a large part of this electricity will come from offshore wind farms, which the report highlights as an economically viable option for Denmark.The Klimakomissionen says many more turbines will have to be erected to cover up to half of the country’s energy consumption.Meanwhile, the energy system will have to become much more flexible and intelligent to cope with the fluctuation of wind energy.Technologies such as smart electricity meters, time-controlled recharging for electric cars and heat pumps in combination with heat storage systems will be crucial to the new energy order.The report says that biomass will play an important role as back up to wind power and to supply heating for homes, along with solar heating, geothermal energy and heat pumps, which will serve district heating systems.

As power consumption falls, it's time for sober second thoughts - 0 views

    here is passing reference to customers maybe using less energy because they're being told to, but it's hardly held up as the biggest explanation. "Something fundamental is going on," says Duke Energy CEO Jim Rogers. He just doesn't know why

Rail Efficiencies - 0 views

  •  
    Environmental organizations and sustainability advocates routinely assert that energy consumption for passenger rail is much "greener" than driving or flying. But Tables 2.13 and 2.14 (summarized in 2.12, above) in the Department of Energy's Transportation Energy Data Book #27 indicate that existing Amtrak intercity passenger rail is only 25% more efficient than the fleet average for cars; furthermore, Amtrak is only 19% more efficient than air travel!

Why on-board hydrogen generators won't boost your mileage | Green News | Eco News - 0 views

  •  
    The marketers out there are selling on-board hydrogen generators which are claimed to provide enough hydrogen to reduce gas consumption by 30-40 percent or more. Is this plausible? Not even close.

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.

Markets, Technology and Institutions: Increasing Energy Efficiency Through Decentralize... - 0 views

  • Project Energy Code focuses on understanding the “green gap”—the individual statements of concern over energy and the environment and the actual decisions and behaviors of individuals with the ability to modify electricity consumption, and the institutions that enable options mentioned above. These Project Energy Code differences between respect to their energy choices. Why does this green gap exist in our electricity consumption choices?

Energy Outlook | The Context of Efficiency - 0 views

  • Here's a nice example of the vital distinction between consumption and efficiency. If I told you that a company was about to introduce a new car model that was expected to average 56 miles per gallon, and that it was going to be so cheap that nearly anyone could afford one, that would sound like great news, wouldn't it? Perhaps it depends on the context in which that car is introduced, and our assumptions about what it will displace. The car in question is Tata Motors' eagerly-awaited "1-Lakh" car--referring to its 100,000 Rupees price equating to $2546 at yesterday's exchange rate--and the target market is millions of Indians who haven't been able to afford a car yet. Even at an expected efficiency of 56 mpg, though, the Nano, to give its proper name, will create incremental consumption of petroleum products and new greenhouse gases emissions.

Green Car Congress: Volvo To Show Flex-Fuel Plug-In Hybrid Concept at Frankfurt - 0 views

  • Based on a Volvo C30, the ReCharge supports a 100 km (62 mile) battery-powered range before the four-cylinder 1.6-liter flex-fuel engine kicks in to power the car and recharge the battery. When driving beyond the 100 km battery range, fuel consumption may vary from 0 to 5.5 liters per 100 km (43 mpg US at full liquid fuel consumption) depending on the distance driven using the engine.

Engineering a Smart Grid For Energy's Future - washingtonpost.com - 0 views

  •  
    The process, Current says, lets a utility more efficiently manage the distribution of electricity by allowing two-way communication between consumers and energy suppliers via the broadband network on the power lines. Based on data they receive from hundreds of homes, utilities can monitor usage and adjust output and pricing in response to demand. Consumers can be rewarded with reduced rates by cutting back on consumption during peak periods. And computerized substations can talk to each other so overloaded circuits hand off electricity to underused ones, helping to prevent blackouts.

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.

Household Energy Use to Triple by 2030, Due to Power-Hungry Electronics - 0 views

  •  
    The IEA says in a new "Gigawatts and Gadgets" report that electricity consumption from power-hungry electronics could cause household energy use to triple by 2030. That means increased greenhouse gases from electric generation, and increased electric bills for creating that power.
