  • Cost breakdown indicates natural gas levelized costs are around 70% variable, while renewables are 80-90% capital

The Case for Natural Gas and Renewable Energy

Highlights: Financial and technological considerations make natural gas, solar, and wind complementary energy sources. Solar and wind have low marginal costs but high capital costs and intermittent generation. Natural gas has low capital costs and are dispatchable but have very volatile fuel costs. Ideal mix of natural gas and renewable energy can meet financial and reliability [...]

  • Natural gas emissions are rising even as coal emissions decline

Is Carbon Capture for Natural Gas the Missing Climate Solution?

Highlights: Several technological factors make natural gas with carbon capture and storage a potentially attractive mid- and long-term energy source. Compared to coal, using carbon capture for natural gas is both cheaper and cleaner. However, due to a lack of ongoing research and demonstration projects, NGCCS is many steps removed from commercial development. With technological [...]

  • EIA LCOE Shows Different Capital and Operating Costs by Technology

9 Reasons Why LCOE Can Mislead

Highlights Despite widespread use, the levelized costs of energy metric has several key limitations. By simplifying costs into one number, it blurs the distinction between capital and operating costs, obscures the importance of interest rates, and implies only one optimal economic outcome. Other operating, economic, and policy assumptions that are critical in forming the metric [...]

  • RPS compliance to grow greatly by 2030

The Future of RPS Policies

Highlights: State level Renewable Portfolio Standards (RPSs) are likely to drive renewable generation to at least 11% of U.S. power supply by 2030. While wind energy historically contributes the most RPS compliant generation, solar is poised to meet increasing portions of RPS demand in the next 5-10 years. Ongoing renewable energy deployments to meet RPS [...]

  • RPS-Compliant renewable generation matches growth in wind

State RPSs Central to Renewable Energy Growth

Highlights State renewable portfolio standards (RPS) have proven essential in driving initial renewable energy growth in the United States. RPS-compliant energy in 2013 constituted almost 5% of total U.S. electricity, with much higher shares in some states. This energy has brought in billions in economic and environmental benefits with limited rate impacts, explaining the political [...]
