Electricity Supply: Sustainable Sources Remain Expensive
Delft, Netherlands (SPX) Oct 09, 2008 Ambitious governments' environmental objectives for the electricity sector are only possible at a high price. This is one of the conclusions of researcher ir. Hans Rodel. He recommends a combination of different modern generation technologies, CO2 capture and storage, the use of biomass and the recycling of waste heat. The government wants to achieve a general CO2 reduction of 30 percent and to increase the proportion of sustainable energy sources within the total energy supply to 20 percent by 2020. According to scientist Hans Rodel this can only be achieved at a very high price in the electricity sector. Scenarios involving a low environmental burden lead to high costs and vice versa. 'One of the conclusions is that electricity from sustainable sources will for the foreseeable future remain more expensive than electricity generated from conventional sources.'
Combination Rodel notes here that CO2 capture technology is still in its infancy and requires further development. Moreover, he believes that the environmental progress made as a result of rapid technological developments in the generation of electricity from fossil fuels is often overlooked.
Scenarios The analysis took as its basis the existing, liberalised electricity supply and aimed to determine whether an effective balance could be achieved for the three key factors: environmental burden, cost of the electricity generation system and certainty of supply. Rodel proposes that the government should at least determine and establish clear growth and stimulatory frameworks for the various production options. 'Choices that are made now will influence the environmental burden, cost and availability of the system for the coming 25 to 40 years.' Related Links Delft University of Technology
Slash Heating Costs This Winter
Lakeville MN (SPX) Oct 08, 2008While caulking cracks around windows and using compact fluorescent light bulbs and ENERGY STAR appliances are smart steps toward conservation, one often-overlooked area that has an immediate impact on home energy use is the fireplace. |
