  • Civilians call the shots. The president decides which wars we enter, sets our strategy, and the number of troops. The Secretary of Defense decides how we fight them. These military bodies – the Joint Chiefs and the Combatant Commands - exist in an advisory capacity. They give their opinions but the military does not bear responsibility for which fights we wage. Civilians are also responsible for Social Policy surrounding the military; i.e. it is not the military that implemented Don’t Ask Don’t Tell … like all other policy, they’re just responsible for enforcing it. These are issues to take up with Congress, or the administration, not the military itself.
  • “Conventional” and “unconventional” sources pertain to the geological formations that the natural gas is found in. Conventional gas is usually free gas and is easier to produce than unconventional sources, which require more complicated extraction techniques. As such, it accounts for more than 90 percent of natural gas produced in the United States. However, unconventional sources like shale are becoming increasingly economical to produce. [Diagram courtesy of EIA]
  • There are many conventional and unconventional sources of natural gas in the United States. The map on the left shows the conventional fields while the map on the left shows shale “plays”, shale formations that contain significant accumulations of natural gas. These plays are large and, in many cases, only small parts of the play have been tapped. In 2010, Shale gas accounted for just over 20 percent of US natural gas production. The Energy Information Administration projects that it will account for nearly 50 percent of natural gas production by 2035. [Diagrams courtesy of EIA]
  • In hydraulic fracturing, water, chemicals, and sand are pumped into a horizontal well in order to create cracks in the shale formation. This allows natural gas to flow from the shale into the well easier, increasing access to large quantities of shale gas. There are several potential benefits. A shale boom could help reduce gas prices and secure our domestic supply. Some estimates also suggest that the boom could lead to about 300,000 – 400,000 new jobs in this country. But fracking has also raised significant environmental concerns, including contamination of local water supplies; the production of large amounts of wastewater, which may contain dissolved chemicals; and, according to the U.S. Geological Survey, small earthquakes.

  • In February 2010, President Obama went so far as to issue a challenge to the federal government: come up with a plan to achieve widespread, cost-effective deployment of carbon capture and storage within 10 years, with a goal of bringing five to 10 commercial demonstration projects online by 2016.
  • By way of comparison, Bureau of labor statistics says - 79,500 Americans work in iron & steel manufacturing. 84,000 work in coal mining.
  • Kilovolt ampere (kilovolt –amp)Bulk energy storage systems are positioned within the high voltage transmission system (115 kVA-230kVA) and are in the domain of the independent system operator (ISO), independent power producer (IPP) and vertically integrated utility. Market drivers include:Enabling more penetration of intermittent renewable resourcesBalancing supply and demand by providing ancillary servicesResponding quickly to system contingencies, e.g. equipment failure, power plant outagesBalancing load and relieving transmission congestionSmoothing or avoiding cycling of thermal power plants being used for frequency regulation or for load followingDistributed energy storage systems fall within city load centers (<69 kVA) at electric utility substations, near feeders, neighborhoods, and at industrial, commercial, residential customer locations. Can be located on either utility or customer side of meter. Market drivers include: Managing electric grid peak demandsImproving reliability and outage mitigationMore effectively using capital expenditures for new grid infrastructureAccommodating distributed renewables and plug in vehicles
  • What does “thermal storage” mean? Is this like freezing water at lower power prices to cool buildings during the day when prices are higher?

    4. 4. Regulated vs. De-RegulatedRegulated • Majority of US electric companies are regulated by state-run Public Utility Commissions (PUCs) • Utilities must get approval from their PUC in order to build power plants, run programs, etc. The PUCs grant the Utility a rate of return on their investment. This regulatory situation is how Utilities operate as monopoliesDe-Regulated (also referred to as Competitive) • Some states, most notably Texas, have broken up the parts of the Generation, Transmission, and Distribution process • Independent Power Generators produce power and sell it directly to consumers • Consumers can select which power provider to get their power • The Utility owning the T&D lines must allow all power to travel through their systems • Has lead to price increases when tried in the past Truman National Security Project 4

    12. 12. Natural Gas vs. Coal Gas cheaper  The price of natural gas is at a 10 year low and has recently dropped below the price of coal (EIA 2011)  Natural gas power generation costs have also fallen  For power generation, natural gas has environmental advantages over coal  Natural gas produces lower quantities of nitrogen oxides and carbon dioxide (CO2) than coal  Emissions of sulfur dioxide and mercury compounds are negligible  Despite environmental benefits of natural gas power generation, over 600 coal fired plants producing between 45% of our electricity (vs. 23% for gas)  Natural gas power generation demand outlook is mixed  Demand for natural gas power generation may increase if policies to place a price on CO2 emissions are adopted  But renewable energy generation resources may reduce natural gas demand for electric power generationTruman National Security Project
    13. 13. Natural Gas: Conventional vs. Unconventional SourcesCONVENTIONAL SOURCES ―Free gas‖ Easier to produce. Accounts for about 94 percent of the gas produced in the U.S.UNCONVENTIONAL SOURCES The increasing availability of Shale gas (which is natural gas trapped in shale formations) has raised its profile among unconventional sources. Other sources include Deep Natural Gas, Tight Natural Gas, Coalbed Methane, Geopressurized Zones, and Methane Hydrates.

    17. 17. Energy (and Environmental) Security Implications Development of U.S. shale gas resources has significantly reduced need for the U.S. to import LNG for at least two to three decades, thereby reducing negative energy-related stress on the U.S. trade deficit and economy. Rising shale gas supply has led to lower domestic natural gas prices, which lowers the costs to average Americans of reducing greenhouse gases as the country moves to lower carbon/non-oil based fuels (e.g., electricity, compressed natural gas). Potential increase in demand for natural gas which can displace high carbon fuels. Increased production by U.S. and other countries weakens ability of long- term potential monopoly power of a ―gas OPEC‖ or a single producer (such as Russia) to use energy resources as a tool for political gain.Truman National Security Project

    25. 25. U.S. Wind EnergyThere is strong bi-partisan support for Wind Energy in the United States.Truman National Security Project
    26. 26. Wind Energy Costs & ProductivityThe Wind Energy Industry has evolved tremendously over the past 20 years. Consistent energy policy is needed in order to allow for continued growth. Truman National Security Project
    27. 27. Installed Wind Energy Capacity Through 2011 State level Renewable Portfolio Standards (RPS) have served as the primary demand driver for the U.S. wind energy industry.Truman National Security Project
    28. 28. Wind Production Tax Credit (PTC)The wind industry is facing therecurrence of the boom-bustcycle it has seen in previousyears when the PTC was allowedto expire. • 60% of a wind turbine‘s value is now produced here in America, compared to 25% prior to 2005. • Over 90% drop in the price of wind power since 1980, benefiting utilities and consumers. • The industry has made ,ore than $60 billion of investment in the U.S. since 2005. Unlike the previous PTC expirations, over 60% of the wind turbine components are now made in the United States by American workers. Truman National Security Project
    29. 29. Wind Industry - U.S. Manufacturing With the threat of the PTC’s expiration, wind project developers are not making plans in the U.S. and American manufacturers are not receiving orders • Over 400 facilities across 43 states manufacture for the wind energy industry. • Layoffs have started already • Historically, in the years following the PTC expiration, installations dropped between 73 and 93%, with the corresponding job losses.If the PTC is not extended, the loss of wind industry manufacturing jobs will impact Americans across the United States. Truman National Security Project
    30. 30. U.S. Transmission• A congested and obsolete power grid limits consumers‘ access to low cost power.• The U.S. Department of Energy has identified transmission limitations as the largest obstacle to realizing the economic, environmental, and energy security benefits of obtaining 20% of our electricity from wind power.• Currently, around 270,000 megawatts of proposed wind projects, are waiting in line to connect to the grid because there is not enough transmission capacity to carry the electricity. Truman National Security Project
    31. 31. U.S. Transmission – Planned Expansions High voltage transmission line expansions are planned throughout the UnitedStates. These capital intensive investments, however, require stable energy policy.Truman National Security Project

    52. 52. Definitions and Benefits?• Energy is the ONLY major sector of the economy in which the product MUST be consumed the moment it is created• Transmission provides energy where it is needed –linking Generation and Consumer in Space• Energy storage provides energy when it is needed - linking Generation and Consumer in Time• Energy Storage buffers disruptions on all levels of the Grid• Load and Generation must be balanced on the Grid • Traditionally, generation was controlled while the load was variable. • With increasing renewable penetration, generation has also become variable. • Penetration of Electric Vehicle use inserts a new and unknown variable• Each type of energy storage technology has its own capital and operating cost structures • The 3 characteristics that matter most in storage are: • Discharge Capacity (MW), otherwise referred to as Power Rating. Is a measurement of how much electricity can be released or absorbed at a given time • Energy Storage Capacity (MWh). Is a measurement of how long energy can be discharged at 1MW Power • Energy Density (MW/volume). This is a measure of how much energy can be stored in a given volume of. The higher this is, the more energy can be stored in a smaller battery.Truman National Security Project
    53. 53. Size Matters Bulk energy storage Distributed energy storage • Mitigates intermittency of renewable energy • Managing electric grid peak demands resources • Balances supply and demand by providing • Improving reliability and outage ancillary services mitigation • Responds quickly to system contingencies, • More effectively using capital e.g. equipment failure, power plant outages • Balances load and relieves transmission expenditures for new grid congestion infrastructure • Smooths thermal power plants used for • Accommodating distributed frequency regulation or load following renewables and plug in vehiclesTruman National Security Project
    54. 54. What can Storage do for US? Reduce risk of grid failure Defer the need to upgrade power-lines and other infrastructure Allows better renewable energy integration System applications (e.g. whereby energy storage provides wholesale market opportunities, energy arbitrage, reduced transmission congestion, lower consumer marginal prices) Commercial, industrial, and residential uninterruptible power supply Make power generation more efficient Reduce greenhouse gas emissions Diminish our reliance on fossil fuels through EV applications Truman National Security Project

    57. 57. The smart grid is a simple upgrade of the 20th century power grids which generally ‘broadcast’ power from a few central power generators to a large number of users to be capable of routing power in more optimal ways to a very wide range of conditions to charge a premium to those who use energy at peak hours orTruman National Security Project inefficiently.

    64. 64. Electricity comes from many different kinds of fuel. Wechose which to use based (largely) on how much each fuelcosts to buy. As you can see, coal and natural gas (known as ―fossil fuels‖) currently dominate. That‘s because they are relatively cheap. Non-fossil sources – such as nuclear, hydro electric and ―renewables‖ – play a smaller role, largely because they are relatively expensive.Truman National Security Project 64
    65. 65. But while cheap to buy, Those costs are not factored fossil fuels come with other into the market. Instead they kinds of costs …. are bared by society. For example: Say a you catch asthma from pollution... Who pays the medical bills? You do. The polluter (decision maker) does not. This is called a ―market failure.‖Truman National Security Project 65
    66. 66. Renewables – such as sun But those benefits are notand wind – are more factored into the market either.expensive to buy, but using For example:them comes with benefits… Say your medical bills drop after a local business replaces a coal generator with a windmill. Who keeps the savings? You do. The business (the decision maker) does not. This is also calledTruman National Security Project a ―market failure‖ 66
    67. 67. How do you fix a market failure?One way is to adjust the price of fuels to reflect the true costs of their use. Two ways to do that: Create A Market. Charge a Tax. Require power plants to buy a Require power plants to pay a “permit” for each ton of pollution flat fee per ton of pollution emitted. emitted. The price per ton is set by supply The price per ton is flat. and demand of “pollution permits” Whichever way you chose, power plants that pollute more (or use more fossil fuels) pay more; those that pollute less (or use more renewables) pay lessTruman National Security Project 67
