Fuel cells are creating a lot of fanfare. But is it warranted? While some say that those hydrogen-oriented devices and the clean byproducts they release are not inevitable, others say that they are playing key roles now that will only grow.

Hydrogen, a carrier of energy, has many applications. It can be used to fuel vehicles, power stations and heavy equipment. One of most burgeoning niches is that of back-up power whereby companies that provide essential services can ill-afford a loss of service and the subsequent revenues. Telecommunications enterprises, for instance, have been pushed by federal regulators and customers alike to beef up their operations and particularly after some natural disasters knocked out services for extended periods.

Solar energy is getting a jumpstart. Energy suppliers scattered throughout the Southwest have asked bidders to submit proposals to build a 250 megawatt solar power project.

The consortium plans on picking a winner by June 2008 so that the project would be completed by 2012. It would be "concentrated solar power" that focuses sunlight, usually with mirrors, to heat a fluid to high temperatures to drive the engine -- something that proponents say can be used for large-scale solar power generation. That differs from the more traditional approach of photovoltaic solar power systems in which light interacts with sheets of semiconductors to generate electricity. That solar technology is more suitable for smaller projects.

Can wind be groomed to become a dependable source of electricity? Researchers at Stanford University say that it can. They conclude that various wind farms can connect and then join at a centralized transmission line to accomplish the mission.

Wind is becoming a premier energy source. But, its intermittent nature means that providers must "insure" against lulls by backing up plants with steadier fuels such as natural gas and coal. If, though, separate wind farms can be linked to a transmission grid, it would make wind more reliable.

The economic impact of wind industry development as the result of Michigan adopting renewable portfolio standards would be significant says a new report released today by the Land Policy Institute at Michigan State University.

The report, titled “Projected Impacts of Renewable Portfolio Standards on Wind Industry Development in Michigan,” is the outgrowth of research lead by Soji Adelaja, institute director and John A. Hannah Distinguished Professor in Land Policy. The report is co-authored by Yohannes Hailu, institute associate director of the Hannah Research Program.

Alternative energy no longer is just a pipe dream of the environmental movement.

Our nation's dependence on an uncertain supply of foreign oil, concerns about carbon dioxide emissions and other factors gradually are boosting the economic viability of developing energy sources that utilize the sun, wind, water and other means.

Gov. Jennifer Granholm wants Michigan to become a leader in alternative energy not so much because of the environmental benefits but rather for the tremendous potential to create jobs in the state.

Dozens of cities and school districts are getting good marks for implementing hybrid buses that run on both diesel and electricity. In doing so, they are helping to commercialize a technology that proponents say will save fuel costs and prevent the release of harmful emissions.

Utilities are making a contribution to the cause. Duke Energy, Progress Energy, Dominion North Carolina Power and North Carolina electric cooperatives are participating with school districts nationally -- all part of a broader business and government consortium interested in seeing electric vehicles take off. The endeavor is well-timed given the attention paid to oil security and climate change along with the technical improvements in battery technology. While commercialization is the ultimate goal market support is still largely absent.
