The Cost of Energy » Document alert: Electric Power Annual - 0 views

  •  
    Electricity generation and electricity sales reached record levels in 2007, according to "Electric Power Annual 2007″, released today by the Energy Information Administration. Following a year of relatively weak growth in 2006, net generation of electric power increased by 2.3 percent, rising to 4,157 million megawatthours and retail sales rose by 2.6 percent to 3,765 million megawatthours in 2007. Continued economic growth in 2007, combined with changes in winter and summer temperatures relative to 2006 that added to electricity use for space heating and cooling requirements, contributed to the increase in electricity sales.

Most Adorable Renewable Energy Video Project Ever (VIDEO) : TreeHugger - 0 views

  •  
    Our Renewable Nation is possibly the most adorable project ever conceived to advocate renewable energy. It's an eco-video project helmed by the McCullough family, who are traveling across the country in a vegetable oil powered VW Beetle. They're visiting wind farms, solar installations, talking to companies developing sustainable technologies, and documenting all their interviews and travels on video. Each of the videos stars 9-year old Carrick McCollough, the cutest kid to campaign in the name of renewable energy. And it's effective. Don't believe me? Just watch the video after the jump, where Carrick implores grownups to not blow it for him and his generation. How can we say no to this?

Solar power a strong contender (ScienceAlert) - 0 views

  •  
    Kramer Junction. Nevada Solar One. Andasol 1. Kimberlina. They're obscure names today. But they'll be household names tomorrow. The reason? Each is now providing 'here and now' proof concentrating solar power (CSP) works. That can't be said for cabon capture and storage. Nor can it be said for 'next generation' nuclear. Each faces years of additional research and development before some 'first mover' will be game enough to build one. That just isn't the case with concentrating solar power. It's got 20 years of proven commercial operation (Kramer Junction) behind it. It also has new innovations coming on line (Nevada Solar One), with solar thermal storage (Andasol 1), and the promise of super-low costs in coming years (Ausra's Kimberlina). What it adds up to is a price-declining research and development juggernaut in concentrating solar power. This is rapidly bringing concentrating solar power closer to competitiveness with dirty fossil fuels. The California Energy Commission estimates this price 'cross over' could happen by 2015. Bulls predict sooner. And in an industry where new plants and equipment can last 40 years, 5-7 years from now is like tomorrow. What this means is that for forward planning of new infrastructure, concentrating solar power is already nipping at the heels of coal. Toss in carbon prices and the reduced likelihood of protesters chaining themselves to bulldozers as they are likely to at any new coal plants, CSP starts looking like a VERY good deal indeed.

Top 7 alternative energies listed: ENN - 0 views

  •  
    The US could replace all its cars and trucks with electric cars powered by wind turbines taking up less than 3 square kilometres - in theory, at least. That's the conclusion of a detailed study ranking 11 types of non-fossil fuels according to their total ecological footprint and their benefit to human health. The study, carried out by Mark Jacobson of the atmosphere and energy programme at Stanford University, found wind power to be by far the most desirable source of energy. Biofuels from corn and plant waste came right at the bottom of the list, along with nuclear power and "clean" coal.

Obama to Add 20 GW of Wind Power in 3 Years : Red, Green, and Blue - 0 views

  •  
    An aide to Obama said Friday that the administration plans to add 20 gigawatts (GW) or more of wind power and 4 GW of geothermal and solar power by 2012 through loan guarantees and fast tracked national renewable energy requirements, like the Renewable Portfolio Standard. Last May the U.S. Energy Department estimated wind power could provide almost a quarter of U.S. electricity. Trade groups from the U.S. wind and solar industries were happy with the news, considering that the current economic environment for commercial credit has lowered all boats as it were, with all investment now endangered - not just investment in risky financial instruments, but even those investments in renewable energy that are essential to growing a stable economy. 4 votesBuzz up! No other country, in any single year, has added the volume of wind capacity that was added to the US electrical grid in 2007 with both wind and solar growing well over 40%, but with the credit crunch affecting all sectors of the economy, new projects could drop by as much as 50%, without help from the Federal government.

If You Can Afford It, New Incentives for Home Energy Efficiency - 0 views

  •  
    2009 brings some new incentives for homeowners to adopt energy efficiency from both state and federal sources. The Wall Street Journal reported last week on several of these, including new provisions for tax credits in solar, small wind, and biomass stoves (those burning wood pellets or corn). In addition, this year, both solar and wind residential tax credits can be claimed against the alternative minimum tax. Improvements to weatherize your home could also qualify for an energy efficiency tax credit of up to $500. There are also new credits for upgrading your furnace, boilers, heat pumps, and water heaters. Read more at WSJ.com: http://tinyurl.com/93n535 Link to original post

Peak Energy: India's will to renewable power - 0 views

  •  
    The Business Spectator has an interesting column on India's growing energy needs and their renewable energy potential - India's will to power. Though blessed with an abundance of non-depleting renewable energy resources, India's record in tapping them has been dismal. Mercifully, of late, renewable sources are getting greater attention. But there is still a long way to go from the 4.9 per cent that renewable energy contributes to total energy generated. The official target is to increase this share to 10 per cent by 2012 and further in subsequent years. ... Among renewable sources, geothermal energy which is derived from natural heat stored in the deep interior of the earth promises to be a key source. Except for a few half-hearted attempts, the government has done practically nothing to exploit this vast reserve.

Peak Energy: Tidal power gets a boost from propeller and wind turbine techonology - 0 views

  •  
    The Guardian has a report on some new tidal power technology from a company in Wales inspired by ship propellers and wind turbines - Tidal power gets a boost from propeller and wind turbine techonology. Propellers on ships have been tried and tested for centuries in the rough and unforgiving environment of the sea: now this long-proven technology will be used in reverse to harness clean energy from the UK's powerful tides. The tides that surge around the UK's coasts could provide up to a quarter of the nation's electricity, without any carbon emissions. But life in the stormy seas is harsh and existing equipment - long-bladed underwater wind turbines - is prone to failure.A Welsh renewable energy company has teamed up with ship propulsion experts to design a new marine turbine which they believe is far more robust.

Peak Energy: Passive Solar Design Techniques - 0 views

  •  
    Will Stewart has a guest post up at The Oil Drum on passive solar design techniques - Passive Solar Design Overview - Part 1. Also, at TOD, a post on the Passivhaus standard from another long-time commenter, marjorian - US Housing and the Passive Home Standard. Passive solar refers to the design and placement of a building to enable solar heating without the need for sensors, actuators, and pumps, in contrast to active solar, which utilizes pumps/blowers, sensors, and logic control units to manage collection, storage, and distribution of heat. The two techniques are not exclusive, however, and can work together effectively. As solar radiation (insolation) is a diffuse energy source, and not at the beck and call of a thermostat, passive solar design techniques are at their best when combined with other related methods, such as energy efficiency (insulation, weatherization, building envelope minimization), daylighting, passive cooling, microclimate landscaping, and a conservation lifestyle (i.e., temperature settings, raising and lowering of insulated shades, etc). Most of these topics will be covered in other articles, though passive cooling will be addressed in this series, which is intended as an overview, as a complete engineering treatment on passive solar design would require several dozens of articles.

Iowa Planning One Billion Dollar Wind Farm : CleanTechnica - 0 views

  •  
    Having almost been run off the road by Iowa's gusty winds, I'm not surprised to hear about the state's interest in wind energy. But the scale of its current project- a one billion dollar wind farm- is truly impressive. The proposed Trade Wind Energy farm will feature 335 wind generators that can produce up to 500 MW of energy. Each generator will be able to power 500 to 1,000 homes. The generators will each be at least 1,000 feet apart, and property owners in the vicinity will receive rent for use of wind rights. Project details haven't been finalized, however, and the number of wind generators will ultimately depend on success in leasing property rights. But Trade Wind Energy representatives are confident that the project will go ahead as planned since some leases have already been signed and area farmers seem receptive.

Japan taps into power of volcanoes with geothermal energy plants - Telegraph - 0 views

  •  
    Japan has announced plans to build its first new geothermal power stations in nearly two decades in a bid to tap the nation's domestic energy sources. A string of geothermal power plants are to be developed by a number of firms keen to capitalise on the active volcanic landscape that spans the country, while the government is also currently compiling guidelines supporting the development of such energy sources. Home to 108 active volcanoes - ten per cent of the world's active volcanoes - Japan is in a prime position to tap into underground geothermal energy sources. As a nation with few natural resources, Japan has long been dependent on importing substantial quantities of crude oil and natural gas. The country's renewed focus on geothermal energy marks a desired shift away from its dependency on imported energy sources which has made it susceptible to increasingly volatile prices.

Newsvine - Organic vs Non-organic - 0 views

  •  
    How important is it to eat organic? Is it a fad, a craze or is it a warning against chemical fertilizers and GMO crops, which will help protect the next generation? Organic farming is natural farming, that means no chemical fertilisers, no genetic modification for either food crops or feed crops. Commercial farming pushing demand for agricultural produce forced a shift towards chemical fertilisers and farming methods to maximise output, for maximum profit, unaware of the significantly unnatural processes being used can be harmful. At the consumer level organic produce is a relatively new phenomena. On the supermarket shelves we are finding products labelled 'organic', most of us think it means 'natural' or 'cruelty free'. When you buy organic you are buying a green product . That means methods such as green fertilisers, crop rotation and biological pest controls are used instead of toxic chemical fertilisers and genetically modified organisms which are harmful to the land. Organic farming composes about 2% of all farming on the planet.

LED Umbrella Is Powered by Rain : TreeHugger - 0 views

  •  
    Part of creating the ultimate sustainable planet will be our ability to find sustainable energy sources in a variety of means, such as sunlight, water flow, wind, and yes, even rain. We are of course speaking of the kinetic energy which can be harnessed from rain, which up until a few months ago, was not being considered for use in a consumer product... Lightdrops Umbrella This kinetic energy is created from piezoelectric material, which is able to convert mechanical energy into electrical energy. Now, we aren't talking about a whole lot of energy being created here, approximately 1 microwatt to 12 milliwatts per rain droplet. While not much in the large scheme of things, this technology has been put to use in a new LED umbrella called Lightdrops, which is able to self power an internal LED light using the rain from which it is protecting its user from.

US Becomes Largest Wind Power Producer in the World : CleanTechnica - 0 views

  •  
    According to the American Wind Energy Association (AWEA), US wind producers enjoyed another record year of growth in 2008-the third in a row. The country now has an installed wind power capacity well in excess of 21,000 megawatts (MW), enough to supply electricity to over 5.5 million American homes. According to Randall Swisher, AWEA Executive DIrector, "Wind energy installations are well ahead of the curve for contributing 20% of the U.S. electric power supply by 2030 as envisioned by the U.S. Department of Energy."

Passive houses, active policies - 0 views

  •  
    The most-emailed NYT article for two days running has not been another explanation of the shaky housing market (that's #2), but rather a front-page story on solidly built "passive houses": Using ultrathick insulation and complex doors and windows, the architect engineers a home encased in an airtight shell, so that barely any heat escapes and barely any cold seeps in. That means a passive house can be warmed not only by the sun, but also by the heat from appliances and even from occupants' bodies. [emphasis added] It's staggering how much energy can be saved this way:
