This World Resources Institute fact sheet provides a framework for comparing the cost-effectiveness of utility-scale renewable energy systems against traditional electricity supply options, focusing on the concept of cost parity from different economic perspectives.

This World Resources Institute fact sheet analyzes how Wisconsin can utilize existing policies and infrastructure to reduce power plant carbon dioxide (CO2) emissions, finding that the state could reduce emissions by 43 percent below 2011 levels by 2020.

This briefing from the World Resources Institute examines the debate over whether greenhouse gas (GHG) reduction policies in the United States should be managed by a single federal authority, individual states, or a cooperative partnership between both levels of government.

This working paper outlines a strategy for the United States to meet its 2025 emissions targets and achieve deeper long-term reductions through a combination of existing administrative authorities, state actions, and future Congressional legislation.

This report by the World Resources Institute provides an overview of the federal policy landscape in the United States regarding greenhouse gas (GHG) mitigation, evaluating existing measures against the goal of a 17 percent emission reduction by 2020 compared to 2005 levels.

This research paper examines the role of local financial institutions (LFIs) in Ethiopia, Kenya, Uganda, and Tanzania in scaling up financing for the Productive Use of Renewable Energy (PURE) sector. It identifies significant demand for PURE technologies, particularly in agriculture, but notes that high up-front costs and LFI constraints—such as limited staff capacity and credit risks—hinder adoption. The paper suggests that LFIs can expand lending through green bonds, climate fund accreditation, and by increasing direct lending from their own balance sheets, supported by blended finance and de-risking instruments from development partners.

This working paper by the World Resources Institute explores how climate finance can catalyze transformational change in low-carbon energy. By analyzing 20 case studies from developed and developing countries, the paper identifies the characteristics of systemic transformation, evaluates specific national experiences, and provides a planning framework and recommendations for recipient governments and development finance institutions.

This working paper by WRI India and TIDE examines the potential for demand aggregation to implement clean energy measures in ten apartment complexes in Bengaluru. The study identifies significant opportunities for energy efficiency (EE) and rooftop solar (RTS) in common areas, while highlighting institutional and policy barriers that hinder adoption.

The Corporate GPM Guide 4, published by the World Resources Institute, introduces the Green Power Analysis Tool, detailing its business rationale, structure, data input processes for projects and corporate targets, and its application in analyzing green power projects.

The 'Glossary of Financing Instruments' is a reference guide produced by the World Resources Institute (WRI) to assist public sector decision-makers in evaluating financing options to support private sector climate change mitigation projects in developing countries.

This document is a testimony provided by Dr. Jonathan Pershing, Director of the Climate, Energy and Pollution Program at the World Resources Institute, to the Commission on Security & Cooperation in Europe. Pershing argues for an integrated policy framework that addresses the intersection of energy security and climate change, asserting that while some energy solutions create trade-offs, others—such as energy efficiency and renewables—provide mutual benefits for both security and the environment.

This report by the World Resources Institute examines how public climate finance can be used to create the policy, institutional, industry, and financial conditions necessary to scale up private and public investment in low-carbon energy. Based on case studies from six developing countries, the report proposes a framework for 'readiness' activities and provides recommendations for international climate funds, specifically the Green Climate Fund.

This fact sheet by the World Resources Institute outlines how Pennsylvania can meet its Clean Power Plan (CPP) emission standards by expanding existing energy efficiency and renewable energy programs, optimizing the operation of natural gas and coal plants, and potentially adopting a market-based carbon pricing program.

This fact sheet by the World Resources Institute (WRI) analyzes how Illinois can utilize existing policies and infrastructure to reduce power plant CO2 emissions, estimating a potential 35 percent reduction below 2011 levels by 2020.

This briefing from the World Resources Institute outlines various policy tools for driving investment in renewable energy, matching specific instruments to the commercial maturity of the technology, from early-stage R&D to mature deployment.

This report introduces an updated geospatial database for clean energy solution providers in Tanzania, delivered via the Energy Access Explorer (EAE) software. The publication demonstrates how standardized, open-access data and multi-criteria analysis (MCA) can be used to identify market expansion opportunities and target investments for mini-grids and other off-grid energy solutions in rural and last-mile communities.

This research paper by the World Resources Institute analyzes Japan's revised 2020 greenhouse gas (GHG) emissions reduction target, known as the "Warsaw Target," in the context of the post-Fukushima energy policy shift. The paper evaluates the target's ambition compared to previous pledges, the current policy landscape, and the likelihood of achieving the goal through electricity-saving efforts and existing mitigation policies.

This research paper by the World Resources Institute examines electricity generation technology options to support the sustainable energy transition of Tamil Nadu (TN). It evaluates the current landscape, technology readiness levels (TRLs), and market potential for various renewable and clean energy sources, including wind, solar PV, bioenergy, energy storage, and green hydrogen, while identifying the policy and infrastructure barriers to their adoption.

This research paper by the World Resources Institute assesses the environmental, energy, and economic impacts of a sludge-to-energy project in Xiangyang City, Hubei Province, China. The project utilizes high-temperature thermal hydrolysis, anaerobic digestion, and methane capture to treat sludge and kitchen waste, converting them into compressed natural gas (CNG) and biochar while reducing greenhouse gas emissions.

This fact sheet by the World Resources Institute (WRI) analyzes how Tennessee can utilize existing infrastructure and clean energy measures to reduce power plant CO2 emissions to meet or exceed EPA standards.
