Better Energy Makes For Lesser Energy Use

Indoor Air Pollution
As per a report in National Geographic, in two small villages on Nicaragua’s Mosquito Coast, a project to improve electricity service had a remarkable side benefit—household energy use actually dropped nearly 30 per cent. When efficient compact-fluorescent (CFL) lightbulbs were added to the mix, energy savings surpassed 40 percent.

“It shows that you can meet development objectives for the poor and climate objectives for all of us at the same time,” said Daniel Kammen, chief technical specialist for renewable energy and energy efficiency at the World Bank, and co-author of an analysis published in the weekly journal Science,The Energy-Poverty-Climate Nexus.

As per National Geographic.com, the study set out to demonstrate a method for measuring both the climate and financial benefits of making investments that improve delivery of reliable, affordable energy for poor communities. Mobilizing such investment is crucial, with 1.5 billion people around the world living without electricity. Another 1 billion people have unreliable electricity, and nearly half the global population relies on unhealthy and polluting wood, charcoal, and dung stoves for cooking.

The United Nations said in a report co-written with the International Energy Agency that its goals for fighting extreme poverty will fall short unless nations also work to bring electricity and modern, safe cooking technology to the “energy-poor” people around the world.

The analytical method outlined in the paper is “very helpful for certain contexts, particularly for looking at how increasing energy efficiency can help support energy access," says Richenda Van Leeuwen, senior director on energy and climate for the the United Nations Foundation, a non-profit that supports the work of the UN. She said she especially sees potential for the approach to be adapted for addressing the global problem of primitive cookstoves. Inefficient wood and waste stoves, used by 3 billion people around the world, create black carbon particulate emissions, a large contributor to climate change, and have a devastating impact on health—especially for women and children.

“There is really room for more research in this area for both traditional cooking and kerosene-based lighting, which both emit smoke,” Van Leeuwen said. “You could begin to monetize the savings of fewer trips to clinics, and fewer treatments for acute pneumonia and other respiratory illnesses that are common among people breathing in cookstove smoke day in and day out.”

Van Leeuwen said the approach is among those being weighed by the new public-private partnership, the Global Alliance for Clean Cookstoves, the United Nations; global energy company Shell and its Shell Foundation; investment bank Morgan Stanley; and the nonprofit SNV-Netherlands Development Organization.

Kammen’s new study underscores the importance of doing a similar analysis for the world’s poor, who can spend more than 30 percent of their income on energy services. In wealthy countries, only 2 to 3 percent of Gross Domestic Product is spent on energy. “Because energy services are often expensive,” said Kammen, “finding ways to provide them more efficiently benefits the poor more than the rich.”
