The People’s Republic of China’s Congress approved a much-anticipated draft of the country’s 12th Five-Year Plan (2011–2015) on March 14. Along with key objectives that included boosting its gross domestic product (GDP) by 7% annually on average, the country for the first time in a five-year plan established targets to tackle climate change. It plans to reduce carbon dioxide emissions per unit of GDP by 17% from 2010 levels by 2015 and to reduce energy consumption per unit of GDP by 16% from 2010 levels by 2015.

One of the main criticisms of renewable energy facilities is that they are unable to dispatch electricity when it’s needed. The great game-changer is low-cost energy storage, which would enable renewable energy production to be stored and rapidly released when needed. Here are seven promising distributed energy storage technologies that could be commercialized in the near future.

Electricity grids are slowly getting smarter. Simultaneously, the use of distributed generation is increasing. Though smart grid advocates tout the ability of a smarter grid to enable greater deployment of distributed resources, the benefits could flow in both directions.

Canada’s extensive natural resources are the driver of its powerful economy, and energy is Canada’s single most important export. Yet policy makers across the nation are currently dealing with the consequences of a generation of under-investment in the electricity system and deciding what the new grid and supply mix should look like. Several provinces are competing to lead the charge in renewable energy and grid intelligence. Policy makers hope that such efforts will not only provide for Canada’s electricity needs but also create the green economy jobs that will drive the nation’s next generation of economic development.

In Canada, as in the U.S., where you live determines the type of generation technology that provides your power. Here’s how the four most energy-intensive provinces in Canada are responding to the challenge of providing reliable and cheap power in a sustainable way.

U.S. Interior Secretary Ken Salazar in late December approved—for the ninth time since October 2010—a solar power project to be built on federal lands.

Though electricity generation has entered a key period of transition—as investment shifts to low-carbon technologies—world electricity demand is set to grow faster than any other “final form of energy,” the International Energy Agency (IEA) says in its latest annual World Energy Outlook.

In November, California voters overwhelmingly rejected an initiative that would have put the brakes on AB 32, the state’s ambitious greenhouse gas (GHG) emissions reduction law. Given the role that California has played in climate change policy, that such a vote took place only four years into the law’s implementation process and 10 years before the emissions reduction targets were to be met was a reality check on climate change policy for those on both sides of the issue.

Scientists at the Massachusetts Institute of Technology (MIT) have a created a set of self-assembling molecules that can turn sunlight into power, and which can repeatedly be broken down and reassembled by adding or removing solution. The scientific breakthrough—inspired by a natural process used by plants to renew light-capturing molecules that have been degraded by the sun—could mean that researchers are closer to creating a self-healing photovoltaic (PV) technology that can keep repairing itself to avoid loss in performance.

The forecast is looking sunny for the 25-MW DeSoto Next Generation Solar Energy Center, which has more than 90,000 photovoltaic (PV) panels and is the largest solar PV plant in the U.S. Completed in October 2009, it is a sustainable energy solution with minimal maintenance costs. The site uses no fuel, consumes no cooling water, has no air emissions, and creates no waste products.
