DOE defines forward plan for energy

Energy Matters0

Population growth and increasing levels of per capita consumption will drive increasing global energy demand in the 21st century. While not preordained, this increase will be large even if the citizens of other countries do not achieve U.S. per capita levels of consumption. Important components of this increase will be in transportation, the fastest growing global energy consumer today (more than 90% of transportation is currently fueled by petroleum-derived fuels) and electrification, which increased dramatically in the 20th century and will increase in the 21st century as well. An important driver of this continued electrification will be the substitution of electricity for liquid transportation fuels.

Today’s world is powered largely by fossil fuels (coal, oil, natural gas) and this will continue well into the 21st century, given large reserves and devoted infrastructure. Nevertheless, fossil fuel resources are finite and their use will eventually have to be restricted. Cost increases and volatility, already occurring, are likely to limit fossil fuel use before resource restrictions become dominant and increasing geographic concentration of supplies in other countries raises serious national security concerns. In addition, the world’s current energy delivery infrastructure is highly vulnerable to natural disasters, terrorist attacks and other breakdowns and energy imports constitute a major drain on U.S. financial resources and allow other countries to exert undue influence on our foreign policy and freedom of action.

Fossil fuel combustion releases CO2 into the atmosphere (unless captured and sequestered), which mixes globally with a long atmospheric lifetime. Most climate scientists believe that increasing CO2 concentrations alter earth’s energy balance with the sun, contributing to global warming.

Nuclear power, a non-CO2 emitting energy source, has significant future potential, but its wqidespread deployment faces several critical issues: cost, power plant safety, radioactive waste storage and weapons nonproliferation.

Globally, energy is not in short supply — e.g., the sun pours 6 million quads of radiation annually into our atmosphere (global energy use: 460 quads).

There is considerable energy under our feet, in the form of hot water and rock heated by radioactive decay in the earth’s core. What is in short supply is inexpensive energy that people are willing to pay for.

Renewable energy (solar, wind, biomass, geothermal, ocean) has significant potential for replacing our current fossil fuel based energy system. The transition will take time but we must quickly get on this path.

Accepting the above, I would recommend the following elements for a national energy policy:

  • Using the bully pulpit, educate the public about energy realities and implications for energy, economic and environmental security.

  • Work with the Congress to establish energy efficiency as the cornerstone of national energy policy.

  • Work with the Congress to provide an economic environment that supports investments in energy efficiency, including appropriate performance standards and incentives. This includes setting a long-term, steadily increasing, predictable price on carbon emissions (in coordination with other countries) that will unleash innovation and create new jobs.

  • Consider setting a floor under oil prices, to insure that energy investments are not undermined by falling prices, and using resulting revenues to address equity and other needs.

  • Work with the Congress to find an acceptable answer to domestic radioactive waste storage, and with other nations to address nuclear power plant safety issues and establish an international regime for ensuring nonproliferation. This includes examination of non-traditional nuclear fuel cycles.

  • Establish a national policy for net metering, to allow individuals and companies to sell electricity to the grid and thus remove an important barrier to widespread deployment of renewable energy systems.

  • Provide incentives to encourage the manufacture and deployment of renewable energy systems that are sufficiently long for markets to develop adequately but are time-limited with a non-disruptive phaseout.

  • Aggressively support establishment of a smart national electrical grid, to enable more efficient use of electricity nationally, to facilitate the use of renewable electricity anywhere in the country, and to mitigate, with increased use of energy storage, the effects of solar and wind energy intermittency.

  • Support an aggressive effort on carbon capture and sequestration, to ascertain quickly its feasibility to allow continued use of our extensive coal resources.

  • Remove incentives for fossil fuels that are historical tax code legacies that distort energy markets and slow the transition to a new, renewables-based, energy system.

I look forward to a stimulating debate, one which has been too long in coming.
