Our cover notes the 100th anniversary of PennWell Corp., which publishes this magazine plus dozens of other business-to-business magazines across a range of industries.

Aside from policy stability, it's probably one of the most widely-cited problems facing the renewable energy industry: The lack of transmission. But is the problem really as big as we're told? Or are utilities using it as an excuse to get more money for an unnecessary build-out of infrastructure and increase profits?

Low prices for power purchase agreements helped kill plans by Idaho Power to buy 150 MW of wind powered electric generation through a request for proposal (RFP) process.

A waste to energy plant has come online in the Clayton Hall Landfill Site near Chorley, in Lancashire. The project is designed to capture methane gas produced from the landfilled waste and convert it into clean electricity that will be fed into the National Grid. Methane is a greenhouse gas that is 21 times more damaging to the environment than carbon dioxide.

We hear so much about the ethanol blend wall, that we can be excused for thinking it is the primary wall, or threshold, out there. The Growth Energy publicity juggernaut ceaselessly reminds us that, at 10 percent blends of ethanol, the U.S. can absorb only about 13 billion gallons of ethanol before it has nowhere to market its ethanol fuel, given the tepid distribution options for E85. But even were the U.S. EPA to approve E15 ethanol blending, there are some other significant walls and thresholds to keep in mind.

We are living in a time when the theory of unlimited economic growth is running into the reality of limited energy sources. To solve the problem, it is commonly thought that renewables are simply a drop-in replacement for oil, gas and coal – but many experts are warning about the faultiness of that assumption.

After a two year delay, Range Fuels is producing methanol fuel from its commercial-scale cellulosic ethanol facility in Georgia. The company initially said the plant in Georgia would be producing up to 20 million gallons of fuel in 2008. Then it got pushed back to 2009. It is now finally operating in the second quarter of 2010.

All eyes are on the energy world with the recent catastrophe in the Gulf, a possible Energy bill in waiting and the increasingly global nature of clean technology. In addition to these market dynamics, there are significant movements in wind, solar, and the development of innovative business models.

Farmers and POET today celebrated the upcoming collection and delivery of 56,000 tons of baled corn cobs and light stover in the first commercial harvest for Project LIBERTY.

Remember BlueFire Ethanol? The company made a lot of headlines back in 2006 and 2007 during the ethanol boom. In an effort to re-brand itself as a more diverse company, It's now BlueFire Renewables.

Business leaders and policy makers from several African countries are set to converge in Berlin Germany this October to explore opportunities in renewable energy in support of much needed infrastructural development and youth employment. The international seminar on Investment Opportunities in Renewable Energy to take place from Oct 4-8 is already attracting strong interests from Rwanda, Ghana and Nigeria, among several other countries. At a time the world is experiencing a wave of environmental disasters, analysts believe investment in renewable is an opportunity whose time has come.

Considering it was an outcome that I very much expected, I still found the U.S. Senate's complete abandonment of carbon cap legislation on July 27 pretty devastating. Beyond the negative effects on the U.S. clean-tech industry and its creation of much-needed jobs, it sends a terrible signal to the rest of the world, particularly China, about America's willingness to finally lead by example on greenhouse gas reduction. In the wake of the acknowledged failure of the global climate talks in Copenhagen last December, the outlook for a meaningful global climate-change agreement is grim indeed.

In a presentation on July 29th, 2010, Ahmad Hadri Haris, the chief technical advisor to Malaysia's Minister of Energy, announced proposed feed-in tariffs for solar photovoltaics (PV), biomass, biogas, and minihydro.

Adage, a biopower joint venture between Areva and Duke Energy, announced last week that it signed a long-term biomass fuel supply agreement with Green Diamond Resource Company, who owns and manages timberland in the immediate area. The $250 million Adage biomass power plant will be located in an area of Washington state called Shelton, which is just southeast of Seattle, Washington.

The military spends a lot of money and manpower getting fossil energies to combat troops. Over the last 4 years, there have been more calls to get modular wind and solar units deployed in places like Iraq and Afghanistan.
