Renewable technologies increase energy sprawl: Nature Newsmillions of hectares of land will be needed to meet growing energy demands in the United states over the next two decades, according to new'energy sprawl'estimates.
The researchers behind the study say that biomass production for fuel or electricity generation will have the biggest impact on landscape and habitats.
The broad analysis of potential US energy and climate-mitigation scenarios compared the land and habitat impacts of various energy mixes from nuclear power to biofuels resulting from an array of policy options.
The study is published this week in PLOS ONE1. In a supplement to the paper the authors re-ran their estimates to take account of the likely impact of the American Clean Energy and Security Act of 2009, also known as the Waxman-Markey bill.
The bill, which is awaiting approval by the US Senate, includes a cap -and-trade system to regulate greenhouse gases.
the amount of land affected by energy development by 2030 will be between 21-70 million hectares an area
A cap-and-trade bill may have some incremental effect in increasing energy sprawl but most of the development that's going to happen is because of other laws that are already in place,
That increase will require an area of between 19 and 31 million hectares the largest component of Mcdonald's projected energy sprawl
despite the fact that biofuels are expected to comprise less than 5%of the country's total energy budget. The US Energy Information Administration predicts that ethanol derived from corn alone might reach annual production levels of 39 billion litres by 2030.
Mcdonald and his colleagues calculate that this would require more than 9 million extra hectares of land to be planted with corn (maize), an area about the size of the state of Indiana.
few studies have evaluated the impact of future energy development on land-use and habitat, says Jimmie Powell,
it's important that we do it carefully to minimize the environmental impacts of these new energy resources.
The authors outline several ways of reducing carbon emissions while limiting energy sprawl. These include energy conservation to reduce the need for additional energy and land use;
proper siting of energy projects to reduce their impact on important habitats and endangered species;
and a flexible cap-and-trade system that allows for offsets that would provide incentives for low-carbon-emitting activities.
but adds that boosting energy efficiency is crucial. We can't emphasize enough that energy conservation may end up being one of our cheapest ways to do this.
