A bill to increase the quantity of solar photovoltaic electricity by providing rebates for the purchase and installation of an additional 10,000,000 solar roofs and additional solar water heating systems with a cumulative capacity of 10,000,000 gallons by 2019.

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``10 Million Solar Roofs and 10 
Million Gallons of Solar Water Heating Act of 2010''.

SEC. 2. FINDINGS.

    Congress finds that--
            (1)(A) there is huge potential for increasing the quantity 
        of electricity produced in the United States from distributed 
        solar photovoltaics and solar water heating systems;
            (B) the use of solar photovoltaics on the roofs of 10 
        percent of existing buildings could meet 70 percent of peak 
        electric demand; and
            (C) a key barrier to increased deployment of solar 
        photovoltaic and hot water heating systems is the upfront cost 
        of capital, even though over time the systems are cost-
        effective;
            (2) investment in solar photovoltaics technology will 
        create economies of scale that will allow the technology to 
        deliver electricity at prices that are competitive with 
        electricity from fossil fuels;
            (3) electricity produced from distributed solar 
        photovoltaics helps to reduce greenhouse gas emissions, does 
        not emit harmful air pollutants, such as mercury, sulfur 
        dioxide, and nitrogen oxides, uses existing rooftop space, and 
        does not require additional land for generation, thereby 
        conserving natural resources and wildlife habitat;
            (4) electricity produced from distributed solar 
        photovoltaics enhances national energy security and helps to 
        meet peak power demand without requiring the construction and 
        siting of new transmission infrastructure;
            (5) investments in renewable energy stimulate the 
        development of green jobs in the United States that provide 
        substantial economic benefits;
            (6)(A) rebate programs in several States have been 
        successful in increasing the quantity of solar energy from 
        distributed solar photovoltaics and solar water heating 
        systems;
            (B) the State of California leads the United States in 
        installed solar photovoltaic systems and has used rebate 
        programs to promote the installation of more than 500 megawatts 
        of grid-connected solar photovoltaics, with 226 megawatts 
        installed during the 3-year period ending on the date of 
        enactment of this Act due to the Solar Initiative of the State;
            (C) the State of New Jersey is second in the United States 
        in installed solar photovoltaic systems and has used incentive 
        programs to achieve 90 megawatts of installed solar capacity;
            (D) the State of Hawaii leads the United States in solar 
        water heating systems installed, and will require all new homes 
        to have solar water heating systems starting in 2010, which is 
        projected to save the average household $600 annually and 
        reduce the oil consumption of the State by 30,000 barrels in 
        2010 alone; and
            (E) the State of Florida has used consumer and business 
        rebate programs for solar photovoltaic and solar water heating 
        systems and is second in the United States in installed solar 
        hot water systems;
            (7) despite inventing solar technology, the United States 
        has fallen behind nations with less solar resources because 
        those nations have set in place policies to promote solar 
        energy, and the United States now ranks fourth in installed 
        solar behind Germany, Spain, and Japan;
            (8) there are more than 1,500,000 solar water heating 
        systems in the United States that rely on a free fuel source, 
        the sun, to provide hot water, and there is enormous potential 
        for additional solar hot water systems to displace fossil fuel 
        use in water heating; and
            (9) homes in the United States spend more than 
        $13,000,000,000 on energy for water heating, which is 
        equivalent to 11.4 barrels of oil per home and accounts for 
        approximately 30 percent of the carbon dioxide emissions of an 
        average home, but solar water heating systems can reduce the 
        cost of water heating and reduce residential carbon dioxide 
        emissions.
