Already renewable energy advocates are noting that the 42 miles of above-ground right-of-way between Yosemite and the city could be fitted with enough solar panels to generate at least 40 megawatts per year - a proposal the San Francisco Public Utilities Commission has never seriously considered because they currently aren't required to do so.

Some types of environmental restoration projects are well-known; restored wetlands, for instance, or coal mine reclamation projects. Recently though, larger dam removal projects have started, a number of them in Washington state.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.

I'm the only candidate which has a policy about how to bring economic opportunity - using clean, renewable energy as the key - into coal country, because we're going to put a lot of coal miners and coal companies out of business.
