In the final Clean Power Plan rule issued August 3, 2015, EPA did not include Energy Efficiency in the calculations used to develop state targets. However, EPA and the White House have made it abundantly clear that energy efficiency remains just as viable a compliance option as before.

The Natural Gas Mystique

The surprising reason why American manufacturing is getting greener.

The newfound abundance of shale gas is not just benefiting utilities using it fuel electric generators. It’s also benefiting manufacturers, which are tapping into basins to fuel their onsite generators.

Electric Vehicle Charging: Tariffs and Tradeoffs

We examine various types of charging strategies and infrastructure available today and report on the experience gained from rate structures for electric vehicle charging now being offered at four different utilities. These findings lead us to provide recommendations to achieve more productive use of the electric grid.

Radical Candor

Finding Common Ground on Energy Efficiency

Policy recommendations for utilities and regulators.

It’s the downright cheapest way of mitigating greenhouse gas emissions. Yet it’s mired from state to state in battles over definitions, principles, and parameters. Herein a collection of recommended policy positions to break the impasse over energy efficiency.

From Coal to Gas

Regulatory and environmental challenges for power plant conversions under the EPA’s Clean Power Plan.

Converting a power plant from coal to natural gas triggers a host of environmental challenges and regulatory issues. Operators could be trading one set of regulatory obligations, liabilities, and costs for another, equally problematic, set of liabilities and costs.
