                Most energy investment is supported by commercial finance and made by private sponsors, but the sources of finance vary widely by technology and region. Today, 75% of the available finance for investment in the energy sector is commercial finance, but domestic and international public finance play important roles that vary widely across regions and sectors.

                Policy options to accelerate distributed solar PV in Ukraine Policy options and implicationsPolicy options and implications

                Overview of policy instruments for distributed solar PV deployment Globally, government policies and incentives have been the main driver for distributed PV deployment. These instruments can be differentiated between 1) policies targeting investment costs and 2) policies focusing on consumption and the sale of electricity.Policies targeting investment costs usually take the form of direct financial incentives that aim to reduce initial investment costs and make distributed PV systems more affordable for consumers. They include:Grants and rebates: a fixed subsidy, usually with a one-time payment.Tax credits: amounts taxpayers can subtract from taxes, usually based on a percentage…

                Outlook for Biogas and Biomethane Assessing the sustainable potential and cost of feedstocks for biogas and biomethaneAssessing the sustainable potential and cost of feedstocks for biogas and biomethane

                Feedstock assessment This assessment considers over 30 types of feedstocks for biogases. They can be broadly grouped together as crop residues, animal manure, biowaste and woody biomass. We assess feedstocks that can be processed without direct competition with food for agricultural land or animal feed, and that do not have any other adverse sustainability impacts. Biogas and methane yields are key indicators of how suitable a feedstock is for energy production. Biogas yield refers to the total volume of gas produced from a feedstock through anaerobic digestion, primarily methane (CH₄) and CO₂. Methane yield, by contrast, accounts only for the…

                Scaling Up Transition Finance Financial institutions and transition financeFinancial institutions and transition finance

                A complementary source of finance for transitions Transition finance rests on a practical partnership between corporates and financiers. Successful transitions need finance that goes where the emissions are; this means moving beyond the top performers and working with corporates with material environmental footprints that commit to transition strategies. A common alternative strategy, in which financial institutions simply shift emissions off their balance sheets, creates “financial carbon leakage” and does not reduce real-economy emissions.An IEA survey of financial institutions revealed that differences in regional taxonomies and frameworks pose challenges for cross-border financing. At the same time, it highlighted…

                Energy Efficiency Policy Toolkit BuildingsBuildings

                Introduction Buildings account for about 30% of final energy consumption globally and more than half of electricity consumption. Doubling the global annual energy intensity improvement by 2030 would require buildings to become more efficient rapidly. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal. Regulatory standards such as building energy codes are among the most effective policies to not only boost energy performance and reduce emissions, but also to improve occupants' health, comfort and productivity – while enhancing climate resilience and mitigating energy price fluctuations. Buildings built after a code is introduced can…
