Technology costs

The cheapest option for generating electricity from biomass is co-firing. Retrofitting a co-firing option to an existing coal-fired power plant costs between $100/kW and $700/kW of biomass generating capacity, with the average price around $200/kW.5

A new direct-fired biomass power plant costs around $2000/kW as a result of the low efficiency of existing technology. This could be reduced to around $1300/kW by the end of the decade as new, higher-efficiency plants are introduced. First generation biomass gasification power plants will probably cost around $2000/kW, dropping to $1400/kW by 2010. For comparison, a typical coal-gasification-based plant entering service in 2006 would cost around $1300/kW.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
