The innovative aspect, I believe, is not the processing of waste cooking oil to biofuel, nor is it the adaptation of a steam boiler to switch to biofuels, but the sourcing of the waste streams from workers who have access to it at home, and who have to come to work every day anyway.
New technology in passenger cars makes biodiesel a much sought after fuel as small diesel motors are now better able to give their gasoline fueled counterparts a run for the money. Reports of 50 mpg results from biodiesel use are becoming commonplace, often in the VW TDI motor and similar models.
So what unknown but magical benefit to nuclear power exists to make nuclear so incredibly attractive to some political leaders? Unfortunately and admittedly, this author does not know.
Since fuel cell solutions can offer business benefits and are ‘zero-emission', they will have an added appeal to consumers and businesses seeking ways to help the environment. As these audiences purchase increased volumes of fuel cell-powered solutions, the potential for a ‘green' future will become more tangible.
A study by the Oak Ridge National Laboratory concludes that with targeted deployment policies, focusing first on New York City and Los Angeles, fuel cell vehicles could achieve 50 percent market share by 2030.
Today, climate change and energy scarcity is driving change, and mature information technology will be the enabling factor to get beyond the fossil-based energy. And, as in previous revolutions, social change will be significant, impacting everything from our daily lives to commerce and politics.
The recent growth in installed capacity along with the expiration of service contracts and the changing characteristic of project owners is pushing the wind service market forward.
We established the Guidance Green Committee to set in motion actions that will help us meet an ambitious yet concrete goal: to operate as an environmentally aware, carbon-neutral company by 2009.
Rainwater systems need not be complicated. They have been built and used for thousands of years.
Powered by cheap oil, the circulatory system of our economy has globalized, expanding populations, wealth, specialization beyond all historical measure. Yet the founding assumption of our success has failed and we are coasting on the momentum of cheap oil. Increasing supply of cheap oil peaked in May 2005. Since that peak gas prices and home foreclosures have skyrocketed as more and more people cannot afford their commute, food and house payments. The evaporation of Bear Stearns indicates the accelerating rate of consequences.
After only three to six weeks of continuous operation, the power costs associated with low-rated electric motors and drives can already have equalled their purchase price.
The National Renewable Energy Laboratory is creating a small wind turbine testing facility, and with the help from industry experts, is creating a testing standard for manufacturers so we can finally compare apples to apples.
It is in defining the brand and communicating it effectively that a company is able to distinguish itself in a very noisy and competitive marketplace.
Renewable energy will be a significant component of our future energy picture -- distributed generation from PVs to wind turbines and storage systems for electricity and cooling. These systems will increasingly be installed in our homes, together with smart electricity meters.
The clean energy sector powered ahead in 2007, according to analysts New Energy Finance. In spite of difficult conditions on the credit markets, the amount of new money invested in the sector grew to $117.2bn, up 35% from 2006's $86.5bn, and more than $20bn ahead of predictions.

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
