Putting Renewable Energy Growth into Perspective

Wind, solar, biomass and other renewable electricity sources grew by 103 gigawatts in 2014, and for the first time in decades, fossil energy's share of world electricity production is declining. Has the great Clean Energy Stagnation of the past three decades finally come to an end?[read more]

The Role of Energy Intensity in Global Decarbonization: How Fast Can We Cut Energy Use?

March 16, 2015 by Jesse Jenkins
21

Energy Efficiency and Cutting Carbon Emissions

Avoiding climate change will require the nearly complete decarbonization of the global energy system, with 50-90% reductions in global CO2 emissions by 2050. These cuts must be achieved against a backdrop of growing global population and projected increases in demand for energy and energy-related services.[read more]

Rooftop Solar Net Metering Problems and Solutions

Net metering policies are effective at supporting solar power adoption but can threaten the financial stability of electricity distribution companies and result in cross-subsidies between electricity users once solar penetration grows. Here's how we fix the problems with net metering...[read more]

Buildings, Renewables, and Grid Integration

Grid operators may have a new ally in their efforts to integrate renewables and regulate the frequency of the grid: buildings. Variable-speed drives used to run heating and cooling systems can be modulated in response to signals from grid operators, helping keep the frequency of electricity flowing across the grid.[read more]

Are Rebound Effects a Problem for Energy Efficiency?

Efficiency Rebound and Value

The New York Times got the headline wrong in "The Problem With Energy Efficiency." Rebound effects are only 'problem' for energy efficiency if you believe efficiency’s unalloyed goal is to cut energy consumption. But that is hardly the case.[read more]

Utilities and Microgrids

Rather than view microgrids as new competitors to traditional electricity distribution utilities, perhaps these local networks of distributed generators, smart electricity loads, and energy storage devices should be seen as a new business opportunity.[read more]

Carbon Capture, Biomass, and Climate Change

According to an international effort to comparing 18 models of the global energy-climate-economic system, efforts to mitigate climate change may depend on two technologies: the ability to capture carbon from power plants and industrial facilities and store it in geological formations and to derive energy from biomass.[read more]
