China Solar Expansion

China is a very difficult solar market to track from the outside. There's no doubt that the Chinese PV market is growing at unprecedented speed. But determining its overall health is more of an art than a science. So perhaps the scientists can help.[read more]

US-Brazil 20% Renewable Commitment is a Good Start, But We Can Do More

July 3, 2015 by NRDC Switchboard

International Renewables Commitments

President Obama and his Brazilian counterpart, Dilma Rousseff, announced a pretty impressive clean energy commitment at their joint White House appearance recently.

Why Should Climate Philanthropy Care About Energy Access?

July 2, 2015 by Justin Guay

Energy Access Efforts

Investing in clean energy access provides a disruptive opportunity to revolutionize electricity systems and get on the right side of the politics of development -- philanthropy just hasn't realized it yet. To be fair, philanthropy needs to step up it's game on climate across the board.[read more]

China and Climate Action

China's climate pledge will require the country to make very significant changes to its emissions trajectory - including adding non-fossil power equivalent to the entire U.S. power generating capacity by 2030. When you compare China's growth trajectory against that of developed countries, how does it compare?[read more]

Solar and the Grid

Solar advocates and opponents have argued over the merits of various studies about the relative costs and benefits of distributed solar PV. Different studies have reached different results -- so different that the Rocky Mountain Institute wrote an entire report just to compare and contrast 16 of them.[read more]

Residential PACE on the Rise; Innovative Solar Financing

Green Investment

Even without access to MLPs, which are publicly traded entities that are allowed to act like traditional corporations in the eyes of the Internal Revenue Service, financing vehicles for clean energy projects are already being unleashed. Investment in clean energy hit nearly $340 billion in 2014.[read more]

Don't Write Off Energy Efficiency, It's Just About to have its Day.

June 30, 2015 by EDF Energy Exchange

The Advent of Energy Efficiency

Economists from the University of Chicago and the University of California, Berkeley released a study that called into question the cost-effectiveness of energy efficiency. The study was based on the team’s analysis of energy savings shortfalls in the Michigan low income Weatherization Assistance Program.[read more]

Solar in the States

As a North Carolinian, I can tell you it's pretty darned amazing that, last year, our state was number 2 in the nation in installed solar capacity. And number 4 in the first quarter of 2015, despite what can only be described as some really crappy (and construction-slowing) winter weather.[read more]

Energy Efficiency Investments Deliver Huge Benefits

June 26, 2015 by NRDC Switchboard

Return on Green Investments

Decades prove energy efficiency programs deliver benefits to consumers and the environment - and these benefits far exceed the costs. A new working paper about a single federal efficiency program for low-income residents in Michigan is generating a lot of hype, but does nothing to contradict these basic facts.[read more]
