Ensuring an adequate supply of rare earth elements and minerals may be a hurdle in the renewable energy supply chain. The metals and their compounds are used in battery technologies, windmills, catalysts, and communications technologies. Add lithium (not a rare earth) to that mix, as Latin American politics could cloud the prospects for new lithium supplies.

"Diversify, diversify, diversify." That has long been the mantra of many Wall Street pundits when advising investors on how to weather the risks of the stock market. Now advocates of electric vehicles (EVs) are using this same logic to champion plug-in hybrid electric vehicles (PHEVs).

Environmental Protection Agency (EPA) Administrator Lisa Jackson defended the science behind the agency’s so-called “endangerment finding” at a Senate hearing on Tuesday—the day after she told coal-state lawmakers that the agency could begin phasing in permit requirements controlling greenhouse gases emitted by large stationary sources beginning in 2011.

The UK’s nuclear safety and security regulator last week raised a regulatory issue against Westinghouse’s AP1000 nuclear reactor design, saying it was not satisfied that the modular construction methodology could protect the third-generation pressurized water reactor from severe weather or physical impact. The finding comes on the heels of a similar issue raised by the […]

A $1 billion settlement negotiated by CPS Energy and Nuclear Innovation North America (NINA) last week ended a bitter legal dispute between the companies and could allow the proposed nuclear expansion of the South Texas Project (STP) near Bay City, Texas, to proceed.

The Department of Energy on Monday conditionally offered California solar company BrightSource Energy more than $1.37 billion in loan guarantees to support construction and start-up of three utility-scale concentrated solar power plants (CSP) in the Mojave Desert of southeastern California.

A draft bill being circulated by Sen. Lindsey Graham (R-S.C.) seeks to create a federal clean electricity standard that could require utilities to supply 13% of electricity from “clean” sources by 2012, reach 25% in 2025, and 50% in 2050.

President Barack Obama on Tuesday offered to conditionally guarantee $8.33 billion in loans for Southern Co.’s project to build two AP1000 nuclear reactors at the Alvin W. Vogtle Electric Generating Plant in Burke, Ga. The pledge marks the first federal nuclear loan guarantee, and it could boost construction of the first U.S. nuclear plant in more than 30 years. More commitments are on the way, the Energy Department said.

BP America, Caterpillar, and ConocoPhillips have pulled out of the U.S. Climate Action Partnership (USCAP), an alliance of business and environmental groups that has been pushing for cap-and-trade legislation.

An executive order issued by Arizona’s Governor Jan Brewer, a Republican, directs the state’s Department of Environmental Quality not to adopt rules under the Western Climate Initiative’s (WCI’s) cap-and-trade program without legislative authorization—but it stops short of withdrawing the state from the coalition that plans to implement a regional emissions trading program by January 2012.

The Arkansas Supreme Court is scheduled on April 15 to hear oral arguments in Southwestern Electric Power Co.’s (SWEPCO’s) appeal of a court decision that took away a permit to build the 600-MW John W. Turk Jr. coal-fired power plant in Hempstead County—the nation’s first ultrasupercritical project.

The first of two new supercritical 615-MW coal-fired units at the $2.3 billion Oak Creek power plant have come online, We Power said last week. Construction continues to complete the second 615-MW unit, and it is expected to be commercially operational later this year.

Ohio-based power company FirstEnergy Corp. last week announced it plans to buy Pennsylvania’s Allegheny Energy in a $4.7 billion deal. The stock-for-stock transaction—valued at $8.5 billion—is expected to create one of the largest U.S. utilities.

By Kennedy Maize Washington, Feb. 15, 2010 — Local opponents of wind farm developments often claim that the energy projects depress their property values. It’s a difficult issue to settle. The Department of Energy’s Lawrence Berkeley National Laboratory claimed last December in a $500,000 study, three years in the works – “The Impact of Wind […]

In their February 10 “state of the industry” speech to the financial community, reprinted here with permission, Edison Electric Institute leaders summarized the challenges and opportunities in the year ahead.

Nuclear was such a target of the environmental movement that it embraced the “anything but nuclear” policy with abandon. Is the movement’s consideration of nuclear now a case of better late than never?

In his recent State of the Union address, President Obama made only a passing reference to the American Clean Energy and Security Act of 2009 (H.R. 2545) passed by the House some months ago. “I’m eager to help advance the bipartisan effort in the Senate,” was President Obama’s acknowledgement that the House approach to controlling carbon in the U.S. faces an uncertain fate in the Senate. However, the Environmental Protection Agency’s (EPA’s) endangerment finding, released on the eve of the Copenhagen meetings last December could be the unnoticed uppercut that follows a weak congressional jab at controlling carbon.

The loading and discharge of conveyor belts is the area where many, if not most, of the problems in solids conveying occur. Fortunately, a new technology provides chutes to accomplish conveyor loading and discharge without blockages while minimizing the dust generated: engineered-flow transfer chutes.

Adding a selective catalytic reduction (SCR) system to an operating coal-fired plant may be an expensive and time-consuming project, but the environmental benefits are without question. However, once construction is complete and operations staff assume control of the SCR, proper measurement tools are required to monitor the catalyst performance life cycle.

Operating a boiler is not difficult, but operating a boiler safely and efficiently requires skill and proper training. Following boiler operation best practices will keep your equipment in like-new condition for years to come. This game plan includes a compendium of best practices, with web links to a number of additional key resources you should be famililar with.

In one of the most far-reaching of numerous new air regulations expected from the Obama administration, the Environmental Protection Agency (EPA) has proposed to tighten the primary federal standard for ground-level ozone, the principal constituent of smog, to within a range of 60 to 70 parts per billion, saying the tougher standard is needed to protect human health.

The Energy Department’s top fossil energy official said [in December that] he might seek exemption or relaxation of “new source review” requirements for certain U.S. coal-fired power plants that are boosting efficiency through retrofits if the plants are also good candidates for subsequent installation of carbon capture and storage systems.

The Energy Information Administraion has predicted that, as the economy gathers steam this year, rising demand for gasoline, crude oil, coal, and natural gas is expected to push up energy prices, aided by a projected boost in crude oil production.
