Uncertainty
“Periods of great uncertainty produce winners and losers; today is such a period. We are living in a world of heightened anxiety about the future of energy.The concern is not just oil, but nearly every aspect of the energy value chain.The stakes are high for all participants in the global economy…”

Obama – August 2008
The Obama‐Biden comprehensive New Energy for America plan will:
• Provide short‐term relief to American families facing pain at the pump • Help create five million new jobs by strategically investing $150 billion over the next ten years to catalyze private efforts to build a clean energy future. • Within 10 years save more oil than we currently import from the Middle East and Venezuela combined • Put 1 million Plug‐In Hybrid cars – cars that can get up to 150 miles per gallon – on the road by 2015, cars that we will work to make sure are built here in America • Ensure 10 percent of our electricity comes from renewable sources by 2012, and 25 percent by 2025 • Implement an economy‐wide cap‐and‐trade program to reduce greenhouse gas emissions 80 percent by 2050
Obama – March 2009
"So we have a choice to make. We can remain one of the world's leading importers of foreign oil, or we can make the investments that would allow us to become the world's leading exporter of renewable energy. We can let climate change continue to go unchecked, or we can help stop it. We can let the jobs of tomorrow be created abroad, or we can create those jobs right here in America and lay the foundation for lasting prosperity.“
-President Obama, March 19, 2009
Obama – June 23, 2009
This week, the House of Representatives is moving ahead on historic legislation that will transform the way we produce and use energy in America. This legislation will spark a clean energy transformation that will reduce our dependence on foreign oil and confront the carbon pollution that threatens our planet. This energy bill will create a set of incentives that will spur the development of new sources of energy, including wind, solar, and geothermal power. It will also spur new energy savings, like efficient windows and other materials that reduce heating costs in the winter and cooling costs in the summer. These incentives will finally make clean energy the profitable kind of energy. And that will lead to the development of new technologies that lead to new industries that could create millions of new jobs in America, jobs that can't be shipped overseas. At a time of great fiscal challenges, this legislation is paid for by the polluters who currently emit the dangerous carbon emissions that contaminate the water we drink and pollute the air we breathe. It also provides assistance to businesses and communities as they make the gradual transition to clean energy technologies. So I believe that this legislation is extraordinarily important for our country.

Renewable Energy Definition
Varies greatly depending on Geographic area Business interest Political interest Included in all (?) Solar Wind Geothermal Biomass Hydro – Low-impact Tidal and Wave Included in most Biomass, landfill gas Included in some Nuclear
Solar Energy
Photovoltaics
Solar cells convert sunlight directly into electricity Photovoltaic efficiency is currently around 15%
Concentrating Systems
Collect and store the sun’s energy in fluid filled pipes using various
mirror mechanisms The energy stored in the fluid can then be used to turn turbines
Passive
Heating and daylighting Incorporated into building design
Water Heating
Various systems used to heat water for building heat and energy,
direct use
Wind Energy
Wind turbines capture energy from the wind Typically mounted 100 feet, or more, above ground Stand-alone applications such as water pumping or
communications Multiple units combined to offset grid power Large, interconnected farms of wind turbines
Geothermal
Energy from the earth captured in various forms Hot water or steam reservoirs deep in the earth Can be used to drive generators to produce electricity
Heat can be pumped into buildings and industrial processes
Geothermal heat pumps can be used to heat/cool homes and
other buildings Heat energy from the hot rock and magma deep in the earth may be harnessed in the future
Biomass
Energy from plant and plant-derived materials Wood, food crops, grassy plants, agriculture and forestry
residues, organic components of municipal and industrial wastes, and methane fumes from landfills Used as fuels and in products as substitute for fossil fuels Controversial because of GHG emissions of burning materials
Hydro Low-impact
Small hydro projects that have minimal total environmental
impact, typically much less than 10 MW Low Impact Hydropower Institute
Certification River flows Water quality Fish passage and protection Watershed protectionT Threatened and endangered species protection Cultural resource protection Recreation Facilities recommended for removal
Tidal and Wave
Tidal energy can be used to create electricity from the large
energy force behind the tides
Use the kinetic energy of moving tides to power turbines
Wave energy is similar to tidal energy, but instead uses the
force behind the waves (not the tide) to generate electricity.
Energy from the rise and fall of the waves captured to create
electricity

What about Hydrogen?
Fuel cells electrochemically combine hydrogen and oxygen
to produce water, electricity, and heat Hydrogen should be viewed as an energy carrier, rather than a fuel Does not occur naturally by itself Must always be separated from other elements Most hydrogen production in the U.S. today comes from steam reforming of natural gas, essentially trading one relatively clean fuel for another Current research on more efficient ways to extract hydrogen and using renewable energy to extract hydrogen
