Back before the stimulus package or the Waxman-Markey bill, when no one was sure whether tax credits for renewable energy would be re-upped or allowed to fade away, U.S. mayors decided to adopt their own climate policy. In signing on to the U.S. Mayors Climate Protection Agreement (a pact to strive for the greenhouse gas reductions targeted by the Kyoto Protocol), cities such as Seattle, Boston, and San Francisco sent a “we’ll do it on our own” statement in response to the lack of federal policy.

Since the launch of the agreement in 2005, some 500 more cities have signed on (and counting). And while some cities just signed the document and moved on, others have used the initiative to draft further innovative strategies that deliver meaningful reductions. The most effective strategies, by far, have been those that bring sustainability initiatives into the office of economic development and turn the city into an early adopter of “green” products and services. It’s exactly this sort of strategy that makes the following cities the best in the country to be a cleantech start-up. In a report, Living Cities Foundation interviewed sustainability directors and gathered data from city sustainability departments throughout the country. We’ve landed on the following seven as the best spots to start and grow a cleantech company (more interviews from the report here).

Today, U.S. Secretary of the Interior Ken Salazar will hold a high-profile public hearing in San Francisco about the future of offshore oil drilling along America’s coastlines.

We have a choice. Invest in safe, renewable forms of ocean energy — including wind, wave, tidal and current power — that will help secure our future prosperity, create thousands of new jobs and reduce our dependence on foreign oil. Alternatively, we can continue to give tax breaks to oil companies that pollute our oceans and keep us locked in a carbon age.

The stakes are high. Oil companies are lining up to cash in on a Bush Administration proposal to offer petroleum development in 1.7 billion acres of formerly protected coastlines, including 136 million acres off the coast of California. This proposal represents a huge step backward. Our country has finally woken up to the need for a green energy future. Now we need to invest in the technology to make America the world leader in renewable energy.

Empowering consumers with actionable intelligence about their power will not be the outcome of the deployment of smart meters. Rather, it will be exactly what the utilities intend for it to be: a cost-effective way to implement real-time pricing, demand side management and distribution system monitoring.

Why? The buyer and seller of electricity have opposite power consumption interests. We (buyers) want to have control over the total power we consume and independent confirmation we are getting what we pay for. Electric utilities (sellers) seek to maximize the profits from a business model that requires them to generate, transport and deliver a consistent quality of power — regardless of demand — in exchange for a guaranteed rate of return.

Electricity generated on the power grid isn’t stored, so the grid is engineered and operated to meet peak levels of demand, which might only exist for a few hours per month. Without control over demand, responding to demand spikes will cause the quality of power supplied to fluctuate outside accepted norms, i.e., delivered voltage lags outside the 5 percent acceptable quality band, or frequency fluctuates outside its 2 percent quality band. That can only change if demand can be controlled, so utilities want three things from smart meters:

As it ventures into renewable energy, 3M is also making strides in its other energy business: batteries. The Minnesota-based manufacturer is already a primary supplier of cathode and anode materials to most of the world’s major battery suppliers and is credited with helping battery makers deliver a higher capacity lithium-ion battery to market.

But now 3M is working on a new material that can make lithium-ion batteries for such products as power tools, laptops and cars lighter. Here’s how it works: Because batteries are comprised of several cells, they typically require an electronic system to keep the cells balanced. “If one cell is doing more than another, you get a disbalance and then your battery won’t charge right,” explains Chris Milker, business manager at 3M.
