Energy Policy Articles and In-Class Discussion

In class today we discussed energy policy in the U.S. and in Brazil and answered questions about the direction each country would like to head.

This assignment is directly for class, but if you're interested, go ahead and read my summaries of them. I included the link to the US one just below.

USA Energy Policy

Oil & Gas stats from the Obama Administration

The President’s climate action plan has three pillars:

·         Cut Carbon Pollution in America
·         Prepare the United States for the Impacts of Climate Change
·         Lead International Efforts to Combat Global Climate Change and Prepare for its Impacts

Because the majority of greenhouse gas (GHG) emissions are tied to energy use and production, a large part of the President’s climate action plan involves changes in energy policy geared towards reducing GHG emissions.
1)      Because power plants contribute to 1/3 of domestic carbon dioxide emissions, the administration has asked the EPA to look into setting federal limits on how much carbon a power plant can emit. State and local limits exist in some places, but federal limits would provide an across-the-board regulation on emissions of new and existing power plants. Internationally, the U.S. invests in clean energy in developing nations by only supporting the highest standard of coal energy or clean renewables.
2)      As An Inconvenient Truth pointed out, the U.S. is behind most countries in fuel economy standards. The Obama administration is increasing the minimum automobile fuel economy in order to attack the emissions from domestic transportation. By 2025, automobile manufacturers will be required to produce vehicles that can attain 54.5 mpg.

3)      Better Buildings is a major initiative supported by the White House which encourages businesses and residences, both public and private, to invest in more efficient housing materials and technologies. The U.S. also invests in modernizing the electrical grid for efficiency, and has made a commitment to double the amount of electricity produced by renewable energy from 2012 to 2020 (this amounts to providing another 10GW, which is enough power to supply 4.4 million homes.

Additional Notes:
·         $8B Loan on research for reduction, avoidance, and sequestration of GHG.
·         Partnerships with battery and fuel-cell companies
·         $250M towards loans and grants for efficient, renewable systems and financing of upfront costs
·         $23M towards looking at new methods to provide cost-effective residential energy
·         Phasing out HFCs, esp. in vehicle AC systems
·         Trying to find ways to reduce methane emissions from coal mines and agriculture
·         Nonspecific forest protection
·         Making gov’t buildings use 20% renewable energy by 2020, as efficiently as possible
·         International agreements so we’re not the only ones making changes
·         Ending $500B/yr in subsidizing activities that encourage fossil fuel consumption
·         Global free trade of clean energy

Natural gas
·         Half as carbon-intensive, Heavy duty vehicles, create worldwide market

Nuclear power
·         Promote safe use

Clean coal
·         Promote development of clean coal technologies internationally

Energy efficiency
·         Clean Energy Ministrial

Brazil Energy Policy

This article provided background information on the current energy production scene in Brazil, and provided 12 policy suggestions based on maximizing key national objectives.

11)      One policy suggestion was to increase the efficiency requirements for household appliances and devices. By doing so, it allows for economies of scale to be reached, so it’s cheaper to produce efficient items that it otherwise would be. Providing incentives to utilities companies that design systems to be more energy efficient is a related measure that allows for modifications more significant than simple appliance gains. The largest project would be adopting energy codes for buildings, depending on zone and purpose. This would have large gains, but would require a large amount of effort in training and implementation.

22)      A primary focus of energy policy is changing the relative contributions of the sources of energy used. For instance, this set of proposal recommends the increase in a method of natural gas energy production called cogeneration, which utilizes both the electricity and heat produced by the combustion process to reduce wasted energy, as opposed to the baseline increase in oil combustion. It also suggests mandating combined cycle natural gas plants, which are more efficient that single cycle natural gas plants, though they are more expensive. The adoption of more grid-connected wind power and off-grid photovoltaic power is also strongly recommended, the latter of which is uniquely suited to provide electricity to rural Brazilians who may not get electricity otherwise.

33)      Lastly, sugar cane production in Brazil is praised and recommended to be continued to make up for less energy being produced by wood and charcoal biomasses. Bagasse, a by-product of the sugar cane ethanol production process, should be used in a more efficient and scaled-up manor, because it has a high potential for energy contribution. Regulating the CO2 output of passenger vehicles will cause a shift towards more ethanol-powered passenger vehicles also.
 Discussion Questions
What policies are in place for each country for fuel sources (oil, natural gas, ethanol, biomass)? What changes do they propose for fuel sources?
A.     The U.S. is rapidly expanding the use of natural gas as an energy source, due to the fact that it produces only about half as much CO2 as does coal. The U.S. possesses large supplies of natural gas stored underground in shales, so this also helps balance our energy trade imbalance. The U.S. is also highly invested in “Clean Coal” technologies, which sound paradoxical, but actually consist of methods to reduce the CO2 emissions of coal, while continuing to use it as an energy source. The U.S. is also open to nuclear energy, however it must meet strict safety standards 
B.     In fact, Brazil is actively engaging in building more fossil fuel power plants, because of the feeling that their energy supply is too dependent on the weather. This feeling was largely due to a power shortage in 2001 brought on by a severe drought. This energy proposal accepted Brazil’s desire for more reliable energy production, and its recently discovered supply of natural gas. It encouraged Brazil to make good choices in this area though, by incorporating cogeneration of electrical and thermal energy in natural gas production, and by regulating highly used plants to be combined cycle as opposed to single cycle.
What policies are in place for renewable energy sources?  What changes in policies do they propose for renewables?
A.     The U.S. seeks to increase their production of electricity from renewable sources. During Obama’s first term, the amount of energy production from renewables doubled, and his goal is to double it again by 2020. This includes the availability of loans and grants to companies who research and develop cleaner, more efficient energy production methods, or ways to conserve energy. As far as inventing new renewable sources, the U.S. funds research projects at universities across the country investigating sources like algae and other bio-based or synthetic fuels.
B.     Brazil has already developed major renewable energy sources. For instance, 90% of its electricity generation (and 40% of overall energy usage) comes from hydroelectric power from state-owned plants located along the country’s vast river system. Brazil is also developing an expansive system of wind turbines which will compare to those in place in Spain, Germany, and the Netherlands. This will add power to their electrical grid and help maintain the proportion of renewables in Brazil, even as new fossil fuels plants are added. For off grid rural areas, the authors suggest the use of photovoltaic energy as a means to provide electrical energy to some that would not otherwise have access.
What do they say the current impact these policies have on the environment, society and economy?
A.     The current policies in the U.S. have a negative impact on the environment, because carbon dioxide emissions are still high, and are contributing to global warming. The policies have been good for the economy and society, however, as industrialization over the last two hundred years has allowed the country incredible advances in wealth and quality of life. However, if changes are not made, the environment impact will affect society in more negative ways.
B.     The current policies in Brazil are also contributing to GHG emissions, though less than the U.S. Their large proportion of renewable energy has been relatively beneficial for the environment, but has had some negative impacts on society in the form of blackouts.
What do they suggest will be impacted or improved with these new energy policies on the environment, society and economy?
A.     New policies in the U.S. will strive to lower carbon dioxide emissions in a way that does not cripple the economy, or cause detriment to society. Regulations will edge us in directions that encourage less energy consumption, or energy production that is less environmentally harmful.

B.     Policy in Brazil will seek to maintain its relatively high proportion of renewables, while reducing its energy imports. It seeks to provide energy to rural areas through photovoltaic energy, and to increase energy efficiency through higher appliance standards and through the adoption of building codes.
