As I’ve written a few times in the recent past, I believe that we have the proverbial cart before the horse when it comes to smart grid. We tend to think of this concept as “futuristic,” like flying cars, when, in fact, it’s what underpins the transition the world is making right now in the direction of energy efficiency, conservation, and renewables.

Although connecting energy efficiency programs and private capital may seem like an ideal partnership, program managers from New York and Pennsylvania have found it is challenging to achieve competitive investment ratings for energy efficiency loan portfolios. Jeff Pitkin and Keith Welks discussed their experiences with accessing the secondary market in (more…)

Lockheed Martin, one of the world’s largest military contractors, has developed a process that company officials say significantly reduces the amount of energy needed to desalinate water, an innovation that could help communities worldwide tackle the growing threat of water scarcity. (more…)

Japanese people have gone back to the streets to protest against plans to reactivate nuclear reactors. Since the Fukushima nuclear disaster, the country has grown wearier of nuclear power and wants an end to atomic power.

The gathering in Tokyo was scheduled to coincide (more…)

A new study concludes that it would be technically and economically feasible for New York State to meet all of its energy needs from renewable sources by 2030, but researchers say the transition would involve building wind, solar, and other alternative energy sources on a mass scale. (more…)

Here’s a good discussion of what I call the “no free lunch” theory of renewable energy: everything we do, whether it’s solar, wind, hydrokinetics, etc., comes with a non-negligible ecological cost. The issue, obviously, is objectively identifying all costs – ecological, financial, and human (e.g., disease and death stemming from various types of energy generation and consumption), (more…)

A Greentech Media piece picked up an interesting item: a recently filed class action lawsuit accusing residential solar provider Sunrun of making deceptive statements about the rising cost of electricity to make its solar installations more attractive to consumers.

The complaint, filed in Los Angeles Superior Court, (more…)

After long and diligent work, my own Commonwealth of Pennsylvania announced last week that it had successfully bundled 4,700 residential energy efficiency loans, and obtained $23 million in cash and $8.3 million in deferred payments, for a projected total of $31.3 million.  The press release is available here.

With early stage capital for cleantech innovation becoming increasingly scarce, crowdfunding sites like Kickstarter, Indiegogo and a new crop of clean/green ones are beginning to emerge as significant sources of funding for selected next-gen clean technologies.

Hurdles remain, particularly for investors seeking returns, but I’m more optimistic about these sites’ (more…)

A national “cool” roof campaign could save some 5.7 quad of net primary energy valued at $33 billion over the 20-year lifespan of an average roof, according to researchers at the Lawrence Berkeley National Laboratory’s Heat Island Group.

The Case for Cool Roofs recommends a no-cost cool (more…)
