Emerging Issues: Integrating Solar Energy

Friday, August 19th, 2016
Figure ES-1. Marginal and average PV LCOE (based on SunShot goals) due to curtailment under increasing penetration of PV in California with low and enhanced grid flexibility

Achieving the U.S. Department of Energy’s SunShot Initiative cost targets could greatly accelerate deployment of grid-integrated solar technologies. Global experience with increasing amounts of wind and solar on power systems has shown that variable generation resources can be integrated into the grid at penetrations well beyond current capacity. However, the prospect of dramatically increased photovoltaic (PV) deployment requires detailed examination to ensure that high-penetration solar technologies will provide their intended benefits, including reducing fossil fuel use and reducing the conventional capacity needed for reliable service.

Vulnerability of the North Alaska Highway to Permafrost Thaw

Monday, August 15th, 2016
Permafrost Melting in Alaska

In the context of current and anticipated climate change, permafrost temperature has warmed significantly in northern territories and is expected to continue to rise (SNAP 2014). The stability of northern transportation infrastructure may be compromised by changes in permafrost, particularly in areas where the soil contains large amounts of ice. This may lead to negative impacts on economic development, including increasing the complexity and cost of road maintenance and the price of shipping goods in the North.

Natural Gas and Global Warming: A Review of Evidence Finds that Methane Leaks Undercut the Climate Benefits of Natural Gas

Friday, August 5th, 2016
Figure 1. Avoiding Climate Tipping Points Requires Immediate Reductions in Methane Emissions

In recent years, a number of studies have challenged that assumption, finding that natural gas production, transportation and storage results in major leaks of methane to the atmosphere that erode or nullify the climate benefits of shifting to natural gas. These findings should lead policymakers to reject natural gas as a “bridge fuel” and instead lead them to redouble America’s efforts to repower with truly clean energy from the sun, the wind and other renewable sources of energy.

Living Shorelines: A Key Line of Defense

Figure 1 Research Finds 14% of U.S. Coastline Is Armored

PEW CHARITABLE TRUSTS
Living shorelines, which use a range of natural stabilization techniques commonly involving the strategic placement of plants, stone, sand, and other materials, provide a proven and cost-effective alternative to structural approaches. These nature-based solutions prevent erosion along estuarine coasts, bays, sheltered coastlines, and rivers while maintaining the land-and-water connection important to sustaining habitats for fish and wildlife, filtering pollutants from stormwater runoff, and protecting land from wave energy.

The True Cost of Fossil Fuels

INTERNATIONAL RENEWABLE ENERGY AGENCY (IRENA)
The reduction of pollution and climate impact through rapidly increased use of renewable energy by 2030 could save up to USD 4.2 trillion per year worldwide, 15 times the associated costs of doubling the share of renewables. Today’s energy markets, however, do not adequately value climate impact or air pollution. Energy and environmental policies need to correct for these externalities.

The State of the Air 2016

Figure 1: Air pollution emissions have dropped steadily since 1970 thanks to the Clean Air Act

AMERICAN LUNG ASSOCIATION
The “State of the Air 2016” found continued improvement in air quality in 2012–2014, showing lower levels of year-round particle pollution and ozone. Still, more than half of all Americans—166 million people—live in counties where they are exposed to unhealthful levels of these pollutants.

Oil Market Futures

Figure ES.1: Global oil demand from transport in 2015 and under two scenarios for 2050

CAMBRIDGE ECONOMETRICS
THE INTERNATIONAL COUNCIL FOR CLEAN TRANSPORTATION
Policies to tackle climate change are likely to lead to lower oil prices, according to the results of this analysis. As governments start implementing the Paris Agreement, they will increasingly need to cut carbon emissions from transport by curbing the combustion of petroleum fuels. Lower oil prices will prevail in this lower-demand scenario, compared to a business-as-usual scenario where oil demand would rise unchecked and in line with economic growth and expanding mobility trends.

Consumer Impacts of California’s Low-Carbon Transportation Policies

Consumer Impacts of California’s Low Carbon Transportation Policies by 2030

CONSUMERS UNION
California is a global leader in developing and implementing clean transportation policies. The State’s regulatory approach is multifold, using various policy instruments to improve the efficiency of vehicles, reduce the carbon intensity of fuels, and increase options for mobility. These policies are a mix of market-based approaches, direct regulation approaches, and planning opportunities. These policies will have impacts on the pricing of consumer goods such as automobiles and fuels– both of which represent a significant share of consumer expenditures.

We Have the Power: 100% Renewable Energy for a Clean, Thriving America

Tuesday, April 12th, 2016
Figure ES-1: Comparison of Renewable Energy Technical Potential and Current Consumption (Data: NREL)

ENVIRONMENT AMERICA
Our transition to a clean energy system has already begun. But, with the need to reduce the pollution that causes global warming growing more urgent every day, we need to step up the pace. To maximize the benefits of moving to 100 percent renewable energy, leaders at all levels must act to accelerate our progress. America’s energy policy should facilitate mass deployment of clean energy solutions, support research and development of new clean energy technologies, and keep much of our coal, oil and gas reserves in the ground.
