The 'Renewable Target' variable defines the minimum percentage of fuel requirements that must be met by processes marked as 'Renewable Qualified'. It is used specifically for optimization-based scenarios to implement Renewable Portfolio Standards (RPS). Users must manually designate processes as renewable qualified at the process level, noting that while wind, solar, hydro, and biomass are typical candidates, certain hydro and biomass projects may not qualify for an RPS depending on the situation.

The Union of Concerned Scientists analyzes a proposal to increase Illinois's RPS to 35% by 2030 and its EEPS to a 20% reduction in electricity demand by 2025. Using the DOE's ReEDS model, the report finds that these strengthened standards would drive $23 billion in clean energy investment, save consumers $12.1 billion in electricity expenditures through 2030, and reduce carbon dioxide emissions by 9.3% compared to a scenario with no policies.

The document evaluates the EIPC's Carbon Reduction Scenario, which aims to reduce carbon emissions in the Eastern Interconnection by 42% below 2005 levels by 2030. Analysis by Synapse Energy Economics indicates that this scenario achieves these reductions with cumulative ratepayer costs through 2040 nearly identical to a 'Business-as-Usual' approach. The scenario relies on a combination of wind energy, energy efficiency, and expanded interregional transmission, specifically projecting 103 GW of new wind in MISO states to support the broader region. The report argues that regional cooperation and updated, lower costs for wind and solar make these targets highly achievable and potentially 30% cheaper than business-as-usual when carbon costs are valued uniformly.

The Union of Concerned Scientists finds that increasing Wisconsin's renewable electricity standard to 25% by 2025 is achievable and affordable. Under the most likely 'No Hydro Imports' scenario, the state would see a $59 million reduction in electricity bills (when accounting for carbon savings), the creation of 2,650 new jobs, and a reduction in CO2 emissions equivalent to removing 2.1 million cars from the road. The analysis highlights Wisconsin's significant technical potential in wind, solar, and biomass to meet these targets while reducing reliance on imported fossil fuels.

WRI analysis indicates that Pennsylvania can reduce its power plant CO2 emissions by 21 percent below 2011 levels by 2020 using existing policies and infrastructure. This would meet or exceed moderately ambitious EPA standards, which are estimated to require reductions between 22 and 31 percent. Key opportunities include meeting alternative energy and energy efficiency targets, increasing the use of combined heat and power (CHP) and natural gas combined cycle (NGCC) plants, and improving coal plant efficiency.

WRI analysis indicates that Arkansas could reduce power sector CO2 emissions by 39 percent below 2011 levels by 2020 through a combination of infrastructure optimization and clean energy strategies. Key opportunities include increasing the utilization of natural gas plants to 75 percent, expanding combined heat and power (CHP) systems, improving coal plant efficiency, meeting energy efficiency targets, and increasing renewable energy sources to 15 percent of the state's electricity.

The analysis finds that most energy supply investments by the World Bank, IFC, and ADB are either aligned with or could be aligned with 2°C pathways under specific conditions. Electricity transmission and distribution (T&D) represent the largest share of financing for the World Bank and ADB, accounting for approximately half of the volume of financing and 40 percent of projects. While renewables projects outnumbered natural gas power generation projects in both number and finance volume, the report warns that natural gas must act as a true 'bridge' by displacing coal rather than adding to it. The study identified 21 oil and gas production projects as 'controversial' due to high emissions and lock-in risk. Misaligned projects often cited strong development rationales, but the authors argue that the urgency of climate change requires transformational rather than incremental improvements. The report recommends that MDBs improve disclosure of indirect financing, shift toward newer technologies like battery storage, and ensure fossil fuel production support is reviewed against G7 commitments to phase out inefficient subsidies by 2025.

WRI analysis indicates that Michigan can reduce its CO2 emissions by 33 percent below 2011 levels by 2020 using current state policies and infrastructure. Key opportunities include meeting the renewable portfolio standard through in-state generation, increasing combined heat and power capacity, fully utilizing existing combined cycle natural gas capacity, and improving the efficiency of coal-fired power plants.

This briefing explores the debate over whether the United States should adopt a single federal climate policy, allow states to lead with individual policies, or utilize a joint approach. It analyzes the rationales for each model, the likelihood of federal preemption of state authority, and the implications for businesses operating across multiple jurisdictions.

The document defines Renewable Electricity Standards (RES) as policies requiring a minimum percentage of electric power to come from eligible renewable sources. It details how these standards create market demand for clean energy, the types of eligible resources, and the potential for business opportunities through the sale of electricity or renewable energy credits (RECs). The text also outlines the state-level adoption of RES in the U.S. as of 2008 and discusses the legislative history and arguments surrounding a proposed national RES.

WRI analysis indicates that Illinois can reduce CO2 emissions by 35 percent below 2011 levels by 2020 using existing policies and infrastructure, which would align with moderately ambitious EPA standards.

Virginia can achieve nearly one-third of its required emission reductions between 2012 and 2030 through planned coal retirements and clean energy investments. To close the remaining gap and surpass targets, the state can pursue a 10 percent reduction in electricity consumption by 2022, a 15 percent renewable energy goal by 2025, and increased utilization of its existing natural gas fleet to 75 percent capacity. The document suggests that adopting a market-based carbon pricing program with a $10 per short ton price for interstate allowances could generate over $100 million in annual revenue between 2022 and 2030. Additionally, robust energy efficiency policies could increase Virginia's GDP by $286 million and add 38,000 jobs by 2030.

WRI analysis indicates that Colorado can reduce its power sector CO2 emissions by 29 percent below 2011 levels by 2020 using existing policies and infrastructure. This would meet or exceed moderately ambitious EPA standards, which WRI estimates would require reductions between 28 and 37 percent. Key opportunities include meeting renewable energy and energy efficiency targets, increasing the use of combined heat and power (CHP), maximizing the capacity of natural gas combined cycle (NGCC) plants, and improving coal plant efficiency.

Wisconsin can achieve 63 percent of its Clean Power Plan (CPP) emission reductions by continuing the Focus on Energy program, maintaining its renewable portfolio standard, and improving the efficiency of natural gas and coal plants. To close the remaining gap and exceed targets, the state could increase efficiency targets to 2.5 percent by 2025 and renewable generation to 30 percent by 2030. The document argues that adopting a market-based carbon pricing program could generate over $100 million annually from out-of-state sources between 2022 and 2030 if allowances trade at $10 per short ton. Additionally, investments in energy efficiency via Focus on Energy provided a 3:1 benefit ratio from 2011-14, saving homes and businesses $1.7 billion.

WRI analysis indicates that Ohio can reduce its CO2 emissions by 27 percent below 2011 levels by 2020 by leveraging existing state policies and infrastructure. Key drivers include the Renewable and Advanced Energy Portfolio Standard (RPS), which could yield a 7 percent reduction, and the Energy Efficiency Resource Standard (EERS), which could provide a 10 percent reduction. Infrastructure opportunities include increasing combined heat and power (CHP) capacity, improving the operating capacity of combined cycle natural gas (NGCC) plants, and enhancing the efficiency of coal-fired power plants.

WRI analysis indicates that North Carolina can reduce its CO2 emissions by 29 percent below 2011 levels by 2020 through a combination of its Renewable Energy and Energy Efficiency Portfolio Standard (REPS), increased combined heat and power (CHP) capacity, fuller utilization of combined cycle natural gas (NGCC) plants, and improved efficiency at coal-fired power plants.

The document advocates for a U.S. national renewable electricity standard (RES) to reduce greenhouse gas emissions, lower energy costs, and position the U.S. as a global leader in renewable technology. It proposes a framework including legally binding targets for all suppliers, eligibility requirements focused on environmental improvement, national sourcing of certificates, and the ability for states to set higher targets.

Virginia can achieve nearly 80 percent of the EPA's emission rate target for 2020-2030 through planned coal plant retirements and the use of combined heat and power (CHP) and natural gas combined cycle (NGCC) plants. To meet the remainder of the target, the state can implement energy efficiency measures to achieve 1.3 percent annual energy savings and increase renewable energy generation to 15 percent by 2025, leveraging untapped wind and solar potential.

The document defines Renewable Energy Certificates (RECs) as tradable instruments representing one megawatt hour (MWh) of renewable electricity generation. It distinguishes between compliance markets, driven by state policies like Renewable Portfolio Standards, and voluntary markets driven by consumer preference. The text highlights the importance of third-party certification, such as Green-e®, to ensure credibility and outlines how factors like technology type and local demand influence pricing. It further clarifies that RECs differ from carbon offsets and explains the distinction between bundled green electricity and unbundled REC purchases.

Xcel Energy's Certified Renewable Percentage (CRP) program enables customers to account for the renewable energy already present in the local grid mix by retiring Renewable Energy Credits (RECs) on their behalf. Launched in Wisconsin and Minnesota, with pending approval in Colorado, the program allows cities and corporations to combine grid-based renewable credits with voluntary purchases, such as the Renewable*Connect program, to reach goals of up to 100% renewable energy. The program's application varies by state based on tariff structures, and Xcel Energy provides calculator tools to help customers determine their specific renewable percentages.
