Wind power hits 57% mark in Colorado
During the early morning hours of April 15, with a steady breeze blowing down Colorado's Front Range, the state's biggest utility set a U.S. record -- nearly 57% of the electricity being generated was coming from wind power.
As dawn came and the 1.4 million customers in Xcel Energy's service district began turning on the lights, toasters and other appliances, the utility's coal and natural gas-fired power plants ramped up production and brought wind's contribution back closer to its 2012 average of 17%.
lities have long been wary of placing too much finicky renewable power on the grid.
"A lot of utilities don't want to contract large amounts of wind because it's volatile," said Amy Grace, a wind analyst at Bloomberg New Energy Finance. "Anything over 25%, and utilities get nervous."
Colorado's overnight high-water mark demonstrated that utilities can indeed incorporate cleaner power sources into the mix.
Renewable Energy Groups Applaud Senate Finance Committee Vote to Enhance Production Tax Credits
Leaders of four renewable energy trade associations today commended a last-minute vote by the Senate Finance Committee yesterday afternoon to extend and enhance production tax credits (PTCs) for all renewable energy sources. The tax credits are essential for the development of clean energy-generating facilities by offsetting the high cost of construction. Yesterday's action by the Committee will give renewable baseload technologies equitable access to this important program by allowing eligible facilities to qualify for the tax credits when construction is commenced.
"We are highly encouraged that the Senate Finance Committee passed this tax credit extension, and we urge the full Senate and the House to approve the credit before the end of the 112th Congress," said Bob Cleaves, President and CEO of Biomass Power Association. "The construction of new biomass facilities can be prohibitively expensive, and our industry relies on one-time tax credits to attract private investors to support the building of new plants. An extension of PTCs will help ensure that renewable energy sources continue to produce a growing share of electricity for our nation."
First Solar Boosting Solar-Panel Production to Meet Higher Demand
U.S. solar company First Solar Inc. (FSLR) said Wednesday that it will make more solar panels this year than earlier planned due to rising demand.
The Arizona company said it plans to make 1,800 to 1,900 megawatts of panels this year, up from its plan in May to cut production to 1,400 to 1,700 megawatts. That compares to 2,400 megawatts of production in 2011.
First Solar Chief Executive Jim Hughes said the company will make more products to meet higher-than-expected demand from customers primarily in Europe and India.
First Solar reported a second-quarter profit of $111 million, or $1.27 a share, up 82% from $61.1 million, or 70 cents a share, a year earlier. Net sales jumped 80% to $957.3 million, primarily due to an increase in the number and size of projects under construction for which revenue could be booked in the second quarter.
Share of First Solar were up 13% at $16.70 in after-hours trade.
Real World PV Solar System Installation - Part 1
AltEnergyMag is having a residential PV system installed and monitoring the process. This is part 1 of a series of articles we will publish along the way in order to demonstrate and explain a real world project for our readers to follow and learn from.
Nuclear Fusion
Research into controlled fusion, with the aim of producing fusion power for the production of electricity, has been conducted for over 60 years. It has been accompanied by extreme scientific and technological difficulties, but has resulted in progress. At present, controlled fusion reactions have been unable to produce break-even (self-sustaining) controlled fusion reactions. Workable designs for a reactor that theoretically will deliver ten times more fusion energy than the amount needed to heat up plasma to required temperatures (see ITER) were originally scheduled to be operational in 2018, however this has been delayed and a new date has not been stated.
SMART GRID SECURITY: A PAN EUROPEAN PERSPECTIVE
The maturity of the smart grid security in Europe could be evaluated as medium to low; that is what our study demonstrated. We are still trying to find out how to implement the smart grid on our electricity power infrastructure, after which we would conceive how the security should be applied. This is not a good approach, we need to define what instruments we should use (requirements for smart grids) in the smart grid before any other action can be taken into account.

"Energy: A Citizens' Solutions Guide" is one of a series of unbiased, nonpartisan guides that help the public wrestle with and work through difficult issues. These guides are especially useful in advance of the election, to help voters cut through campaign spin and media bias, so that they are able to reasonably judge the platforms put forth by candidates.
Energy through Hydrogen
In many ways, hydrogen is the perfect fuel. It's abundant, efficient and produces no emissions when used in a fuel cell. It can be produced from renewable resources and is not a greenhouse gas. Because hydrogen power is environmentally friendly and non-toxic to use, industry should accelerate research so that this renewable resource may be used in the near future.

Corruption and Mismanagement See Much of the US without Power
Americans are now being told that keeping utility bills down means keeping maintenance of the country's dismal electricity distribution system to a bare minimum. According to the American Society of Civil Engineers, the entire system could collapse by 2020 without an immediate investment of $673 billion. Furthermore, experts say that brownouts and blackouts will end up costing more in the end than re-hauling the entire system.
The Birth of After-Market Consumer Electric Drive
You climb in and start your car. Reverse out of your driveway using the gas-powered system. Putting the shift lever into neutral, the system switches over to the AED (Alternative Electric Drive) system, yet your engine is idling. This allows you to use your power brakes, power steering and air-conditioner on that hot muggy day.
