Solar to provide 10% of U.S. electricity by 2025 – study

18 June 2008 | Market Watch: News

SolarA new study by clean-tech research publisher Clean Edge and Co-op America, a non-profit green-economy organization, has suggested that the U.S. could attain production of 10% of its electricity requirements via solar power by the year 2025. The Utility Solar Assessment (USA) study provides a roadmap for use by utilities and regulators, as well as solar power companies, which outlines the necessity for involvement of utilities in scaling solar power in order to reach the 10% goal.

The study claims that solar power should be viewed as a cost-effective measure of electricity generation that can rival current electricity costs while steering away from the use of fossil fuels that are becoming more and more costly every day. The data in the study were compiled based on interviews with more than 30 solar, utility, financial, and policy experts.
 
Projections for solar energy prices are expected to decline from an average $5.50-$7.00 peak watt (15-32 cents kWh) today to $3.02-$3.82 peak watt (8-18 cents kWh) in 2015. A further decrease in cost to $1.43-$1.82 peak watt (4-8 cents kWh) is anticipated by 2025, according to the study.

A comprehensive “to-do” list was provided for each of the players (utilities, solar companies, regulators), outlining the steps that need to be taken by each in order to contribute to the combined effort and thereby to achieve the 10% goal by 2025. Further information on the study is available here.

A more efficient and cost effective renewable energy system is needed. To accelerate the implementation of renewable electric generation with added incentives and a FASTER PAYBACK - ROI. (A method of storing energy, would accelerate the use of renewable energy) A greater tax credit, accelerated depreciation, funding scientific research and pay as you save utility billing. (Reduce and or eliminates the tax on implementing energy efficiency, eliminate increase in Real estate Taxes for energy efficiency improvement). In California, you also have the impediment, that when there are an interruption of power supply by the Utility you the consumer cannot use your renewable energy system to provide power. In today's technology there is automatic switching equipment that would disconnect the consumer from the grid, which would permit renewable generation for the consumer even during power interruption. Energy storage technology must advance substantially. “Energy conservation through energy storage”. New competition for the world's limited oil and natural gas supplies is increasing global demand like never before. Reserves are dwindling. These and other factors are forcing energy prices to skyrocket here at home. It's affecting not just the fuel for our cars and homes, but it's driving up electricity costs, too. A new world is emerging. The energy decisions our nation makes today will have huge implications into the next century. A synchronous system with batteries allows the blending of a PV with grid power, but also offers the advantage of “islanding” in case of a power failure. A synchronous system automatically disconnects the utility power from the house and operates like an off-grid home during power failures. This system, however, is more costly and loses some of the efficiency advantages of a battery-less system. We’re surrounded by energy — sun, wind, water. The problem is harnessing it in an economical way. Jay Draiman, Northridge, CA June 19, 2008
