This latest report from Business Insights provides a overview of the green energy market in the US. The generation of electricity in the US is still dominated by coal with 48.5% of the total US electric power generated at coal-fired plants in 2008. In the same period renewable energy, predominantly hydroelectricity, contributed 9.1% of the total power generated in the US. However the outlook for renewable energy looks encouraging as the introduction of the federal Production Tax Credit (PTC) combined with the Renewable Portfolio Standards (RPS) by several states has spurred investment in this sector. Other drivers in favour of renewable energy include strong public interest in addressing climate change and political willingness to introduce change.
Highlights from the report:
Wind Power: the largest market globally, in terms of installed capacity. Key challenges are environmental concerns as well as transmission infrastructure bottlenecks and high transmission costs associated with evacuating wind power from areas where it is produced to where it is consumed.
Solar Energy: the key challenge that solar power faces is that it continues to require significant upfront investment. Another near term challenge is the shortage of silicon which is a primary raw material for the PV industry. The potential for solar energy in the US is estimated to be significantly higher than in Germany or Japan, the current leaders in the solar industry. In particular, the US has extremely rich solar resources in the Southwest region.
Hydropower: the US is the second largest producer of hydropower globally. Key challenges are concerns about the environmental impact of hydroelectric plants, lack of incentives and higher initial development costs.
Geothermal power: the US is the world leader in geothermal energy. Key challenges for geothermal power include leasing and permitting delays and transmission issues combined with scant funding for geothermal research programs. In addition, the project cycle for geothermal projects development is often longer than the time window for which PTC is currently available.
Biomass: the total installed biomass (biomass energy used to generate electricity) capacity in the US was over 10,900 MW at the end of 2008, making it the largest producer of biomass globally. Key challenges in the way of increased biomass generation include the lack of strong incentives and subsidies and constraints in the supply of raw materials.
Ocean power: this is still very much in its infancy in the US and there is no significant installed capacity in the country yet. Key challenges include high generation costs and leasing and permitting issues. It is estimated that the US ocean wave resource potential is roughly 5.0% of the total US electricity supply. US tidal energy is estimated to have enough potential to address roughly 2.5% of the total US electricity supply.
