Health
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores health. Why is energy efficiency important for health? Energy efficiency can improve health by creating healthy indoor and outdoor living environments with comfortable temperatures and humidity levels, and improved air quality. Key facts Energy efficiency measures have been linked to improved health, such as fewer respiratory illnesses.Targeted energy efficiency programmes can reduce doctor and hospital visits and save health costs. In New Zealand, a retrofit programme led to a 43% reduction in hospital admissions for respiratory conditions, while a similar programme in Ireland reduced the…

Renewables for Industry Executive summary
Electrification of heat can improve efficiency, help diversify industrial energy, and enhance energy security A broad range of industries that depend primarily on low-temperature heat and steam processes represent roughly 70% of global industrial energy consumption. They span diverse manufacturing activities – from food and beverages to textiles, chemicals, transport equipment, wood products and paper. In 2023, these sectors emitted nearly 3 Gt of direct energy-related CO₂, accounting for half of all direct industrial emissions, although emissions have declined by around 8% since 2013.Industrial energy use is largely in the form of heat and is increasingly being supplied…

Renewables in District Energy
This report examines how renewables can play a larger role in district energy systems, helping to deliver cleaner, more secure and more efficient heating and cooling. District energy networks already supply heat to around 600 million people worldwide, but many systems remain heavily dependent on fossil fuels, exposing consumers and utilities to price volatility, supply risks and high emissions.The report provides a global overview of district energy systems, their fuel mixes, market conditions, governance models and affordability implications. It explores the growing opportunities offered by renewable and recovered heat sources, including bioenergy, geothermal, solar thermal, waste heat, large-scale heat…

Ramping up Heat Pumps in Moldova: A Roadmap Financing the transition
This chapter considers the economics of heat pumps versus gas boilers and biomass stoves. It explores the role of grants and subsidies and how these affect the lifetime cost of owning a heat pump compared to other heating technologies. Different policy options are then discussed, including potential avenues for multi-lateral policy support at both national and local levels. As previously mentioned, a main barrier to heat pump adoption is the high upfront cost relative to prevailing heating technologies. Governments can help to lower this hurdle through mechanisms such as upfront subsidies or grants and low-interest loans. Another way…

Emission reductions
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores emission reductions. Why is energy efficiency important for emission reductions? Energy efficiency can reduce emissions of greenhouse gases and air pollutants and make the energy system more sustainable. Key facts Since 2010, efficiency measures avoided energy-related carbon dioxide (CO₂) emissions equivalent to nearly 20% of the global total in 2023. This is more than the entire energy-related emissions of India and the European Union combined. Accelerating efficiency improvements could deliver a third of all energy-related CO₂ emission reductions between now and 2030 in…
