Majority Leader Harry Reid (D-NV) released details of the energy bill he is putting before the Senate on Tuesday, making it official that any hope for a national renewable electricity standard (RES) is dead. Last week Reid said as much while foreshadowing the contents of his bill, which focuses more on oil spill response than renewable energy. Since then, dozens of democratic senators (including one republican) and industry groups pressed Reid for, at the least, inclusion of a national RES to promote a shift to cleaner power over the long term.
For at least the short term, any RES prospect has been declared dead by the one man who could have given it life.

To make matters worse, the bill excludes just about everything else that could really help the renewable energy industry, especially the troubled wind sector, which has seen quarterly figures drop 71 percent from the same time last year.
NOT included are:
What the bill does offer:
The oil industry is railing against the bill, which means it must be doing something right. Yet while incentives for electric vehicles, increased oil regulation (so obviously lacking in the lead up to the BP spill) and energy efficiency incentives are good steps, this can hardly be called an energy bill — at least not in the sense that the renewable energy industry, President Obama, nor any environmental advocate had hoped for.
Harry Reid and other Senate Democrats admit that the bill is far from sweeping, but claim that it’s the best they can do without a guaranteed, filibuster-proof 60 votes — something Reid says they most certainly do not have. And even this gutted sham of a climate change bill faces stiff opposition from republicans, whose main objective seems to be to oppose anything and everything until the GOP has a chance at regaining power in November. Although, they apparently have all the power they need already, or at least enough to stop the less-than-brave democrats tiptoeing around the Senate floor and all over the progress-minded constituents that voted them in nearly two years ago.
And where’s President Obama on all this? Good question.
Despite Senate Majority Leader Harry Reid’s assurances that no such provision will be included in a climate bill this summer, 27 Democrats and one Senate Republican are nonetheless pressing the Nevada senator for inclusion of a renewable electricity standard (RES).
An RES would require utilities to obtain a percentage of their power from renewable resources within a set time frame, and is considered one of the best ways to promote clean energy production in the United States over the long term. Last week, Reid came out saying that such language was not in his vocabulary.
Sam Brownback of Kansas (a state that already gets 20 percent of its electricity from wind power) is the lone Republican senator to join Democrats in signing the letter urging Reid to include a national RES in his bill. Brownback is, however, staunchly opposed to any carbon cap or tax being included.
Reid and many other Democrats in the Senate are apparently fearful of a Republican filibuster because they do not have the 60 votes necessary to nullify that option (although, why they don’t force the Republicans’ hand instead of constantly allowing the opposite is beyond me).
Still, Brownback and his unlikely Democratic allies believe they can get the 60 votes and that there is enough bipartisan support in the Senate to pull off an RES-inclusive bill.
Senators Byron Dorgan of North Dakota, Mark Udall of Colorado and Tom Udall of New Mexico led in drafting the letter, which argued, “A strong RES will give certainty to clean energy companies that are looking to invest billions of dollars in the U.S. to manufacture wind turbines, solar panels and other renewable energy components.”
29 states already have their own renewable energy mandates, but legislation would have to be uniform throughout the country to truly facilitate wide-scale, permanent growth in the national renewable energy industry.
The main opposition to a national RES comes from senators of both parties representing the American South, where only four states — Delaware, Maryland, North Carolina and Texas — have state-level RES portfolios.
Many of these states are rich in coal and have a strong lobby against any legislation that would tax or otherwise inhibit its production. Senators from these states often argue that their states do not have the renewable resources that other states have, such as the Southwest’s sunshine or wind along the coasts and in the Midwest. Subsequently, their states would be at a disadvantage when trying to meet RES requirements and would pay an unfair amount of penalties for noncompliance.
However, Environmental Leader reports that a new study, Renewable Energy in the South, released by the Georgia Institute of Technology and Duke University, asserts that a national RES would be an economic boon to the South. It claims that southern states could obtain 20 to 30 percent of their energy from renewable resources within 20 years if strong federal mandates are passed, all while adding thousands of new jobs. The South gets less than 4 percent of its energy from renewables today. Most of what there is comes from hydropower.
Yet despite letters, broad support outside the South and intense pressure from RE industries, nearly all hope for a strong climate bill coming out of the Senate this year is gone. The heavily compromised bill Harry Reid is expected to release this summer will include some minor but largely ineffectual clean energy incentives and some oil and gas industry regulations in response to the BP oil spill. Reid has shown no signs yet of relenting on his no-cap, no-RES position.

PARIS, July 28, 2010 /PRNewswire-FirstCall/ –
- Containerized Lithium-ion Energy Storage Battery Marks Major Step in Viability of Renewable Energy Sources
Saft has announced a three-year deal to work with Spain’s Acciona Energia SA as part of a Eurogia+ labelled project aimed at improving the viability of photovoltaic and other renewable energy source power plants. The project will demonstrate the technical and financial benefits of using a containerized energy storage, conversion and management system to provide grid ancillary services as well as power management to help smooth the plant output.
As part of the initial project at a photovoltaic (PV) plant in Tudela, Spain, Saft will develop a modular lithium-ion (Li-ion) battery system to be housed inside a six-meter container designed for industrial applications. The container includes active temperature control systems and a fire suppression system. The long-life Li-ion battery offers very high energy-efficiency, no battery maintenance and an easy way to measure the battery state of charge even while in use.
The project also seeks to integrate PV plants within the grid as conventional power plants by means of new control systems to be developed by Acciona Energia, including test of new PV technologies, with a final aim of reducing the Cost of Energy (LCOE) and providing additional services such as ancillary services, improving grid stability and back up power security.
“With the ever increasing contribution of renewables in our electricity mix, it is of crucial importance to improve the electrical behaviour of renewable power plants The decision to work with Saft on this project was a natural one”, said Miguel Arraras, Solar PV Development Director Acciona Energia. “In addition to their batteries high energy-efficiency and reliability, their containerized solution is ideal when it comes to addressing environmental constraints of field deployment. Saft’s knowledge of designing, manufacturing and controlling large energy storage systems means it will be a key contributor to the partnership.”
As part of the system, Saft will be able to offer the customer 1.1MW power at up to 1,000V. Each container is easily scalable and will interface with existing power conversion devices.
“We are delighted to be working with Acciona on this groundbreaking project,” said Francois Bouchon, Director of the Energy Storage Business Unit, Saft. “We believe the introduction of containerized energy storage makes photovoltaic and other renewable energy source plants an increasingly attractive option for the future. The ability to address issues around reliability, stability and power management is a huge step for the power industry in its efforts to integrate ecological concerns.”
For 20 years, SEI has been at the forefront of solar PV training.
