The role of biomass as a primary energy resource is highly debated. Next generation biofuels are suggested to be associated with low specific greenhouse gas emissions. But land consumption, demand for scarce water, competition with food production and harmful indirect land-use effects put a question mark over the beneficial effects of bioenergy deployment. In this…

Market and Policy Barriers to Deployment of Energy Storage
There has recently been resurgent interest in energy storage, due to a number of developments in the electricity industry. Despite this interest, very little storage, beyond some small demonstration projects, has been deployed recently. While technical issues, such as cost, device efficiency, and other technical characteristics are often listed as barriers to storage, there are…
Solar Integration
Solar energy can enter our energy systems through many doors and windows, mostly as heat and electricity. As costs go down, especially for photovoltaic electricity, the variability of the resource becomes a dominant issue.Interconnections,load management, flexible fossil or hydro power plants and storage capacities of pumped hydro plants combine to make the daily variability manageable,…
Contracting for Wind Generation
The UK Government proposes offering long-term Feed-in-Tariffs (FiTs) to low-carbon generation to reduce risk and encourage new entrants. Their preference is for a Contract-for-Difference (CfD) for all generation regardless of type. I argue that a standard CfD is unsuitable for on-shore wind, where a fixed FiT appears less risky. The estimated extra trading and balancing…

Is the Grass Greener on the Other Side?
I investigate whether households face reduced access to energy efficient goods in low income and minority neighborhoods. Using data from 27,000 zip codes, I uncover empirical regularities in access to three categories of ENERGYSTAR@ goods: light bulbs, electronics, and appliances. I find that (1) lower income neighborhoods experience reduced access to ENERGYSTAR@ goods; and that…
What was the “discrepancy” in Japan’s energy policy after Fukushima nuclear crisis?
After the Fukushima nuclear crisis following the Great East Japan Earthquake of March 11, 2011, it is not correct to say that Japan decided to change energy policy dramatically from a fuel mix heavily reliant on nuclear power to one involving growing use of renewable power. Nor is it correct to say that Japan intends…

Market Power and Generation from Renewables: the Case of Wind in the South Australian Electricity Market
This paper examines whether outcomes in the electricity market in South Australia are consistent with theoretical analysis and market modelling that concluded that intermittent generation benefits less from market power than conventional generation. The paper finds that, based on actual outcomes in South Australia over the period from 2006 to 2011, the exercise of market…
Distributional Effects of Energy Transition: Impacts of Renewable Electricity Support in Germany
The discussion of the support for renewable energy must consider the distributional impact of cost allocation. The public is sensitive to social imbalances caused by rising power prices that might jeopardize the acceptance of energy transformation. By the end of 2012 about 19 percent of German power is produced with renewables other than hydropower. As…
