80% of all energy could be from renewables by 2050...with the right policies

May, 2011
Development in a Changing Climate
In just one day, the sun delivers about as much energy as has been consumed by all human beings over the past 35 years. So why haven’t we exploited more than a tiny fraction of this potential? There are many reasons: cost, storage, transmission, distribution, entrenched subsidies and technological challenges are but a few of them.

But the reasons not to take advantage of renewable energy are falling away. A report published this week by the Intergovernmental Panel on Climate Change (IPCC) found that close to 80% of the world’s energy demand could be met by tapping renewable sources by 2050, if backed by the right enabling public policies. I served as a Coordinating Lead Author for the Policy and Deployment chapter of the report, as well as member of the Summary for Policy Maker’s team, and I can attest to how much rigorous analysis and effort comparing data and sources went into this process and document.

Time to Clear the Smoke

June, 2011
The Great Energy Challenge
In many parts of the world, a picture of a woman sitting in front of a smoky cookstove preparing a family meal remains an iconic picture of life today. For many families, the three- stone fire or a traditional stove as a cooking device has not changed over centuries. This need not be the case, and in a growing number of nations, that traditional pattern is changing.

Serious research on improved cookstoves dates back to the 1950s. However, large-scale field programs focused largely on the inefficiency of designs. While the stoves may appear simple, the socio-cultural systems in which they operate, and their impacts on so many aspects of household and regional health and economics, is far from simple. Many approaches have been tried, with some successes and many failures.

Over the last few years, a more complete view of the full human and environmental health impacts of indoor air pollution and the global impact of the fuel and stove cycle has emerged. Poorly managed fuel systems encourage use of unsustainably harvested fuel such as charcoal produced from illegal and ecologically damaging informal production network.

Biofuels: Threat or opportunity for women?

May, 2011
Development in a Changing Climate Blog
In Africa, where two-thirds of farmers are women, the potential of biofuels as a low or lower-carbon alternative fuel, with applications at the household energy, community and village level, to a national resource or export commodity, has a critical gender dimension. The key question is: how will increased biofuel production affect women?

To look at the impacts on women, one logical approach is to use a computable general equilibrium model that tracks economic impacts of new crops and how patterns of trade and substitution will change. It’s important to account for the complexities involved, and rely not on a simple, traditional commodity model but one that tracks the impacts on women through changing prices and demands for crops to be sold on local and international markets. Who gains and who loses as prices change, and as the value of specific crops and of land changes?
