                Affordability

                Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores affordability. Why is energy efficiency important for affordability? Energy efficiency measures can reduce energy bills for households, decrease energy poverty, and make access to energy services more affordable. Key facts Energy efficiency measures can reduce average household energy bills in advanced economies by up to one-third. In emerging economies, they can also improve access to energy services. For many products, such as refrigerators, highly efficient models use less than half of the energy of inefficient models. A best-in-class model can save up to…

Ireland is scaling infrastructure and modernising operations further to reach its goals of 80% renewable electricity by 2030 and running a system almost entirely from wind, solar, storage and imports by 2035, while managing growing electricity demand from the housing, data centre, heat and transport sectors.To support decision makers as they plan for the future, this report introduces a pathway that explores what would be required to maintain electricity security while advancing towards Ireland’s ambitions.

                Critical Minerals

                Critical minerals are essential for a range of today’s energy technologies and for the broader economy. For example, lithium, nickel, cobalt, manganese and graphite are crucial to battery performance. Rare earth elements are essential indispensable to the permanent magnets used in wind turbines and electric vehicle motors. Electricity networks need a huge amount of aluminium and copper, the latter of which is the cornerstone of all electricity-related technologies. As demand for these materials grows strongly, their strategic importance has also increased – and policymakers have made ensuring secure and resilient mineral supply chains a major priority.

                Angola is set to become the largest producer of crude oil in Southern Africa, yet has also set the foundation for the sustainable development of renewables, through investments and supportive measures. Angola has particularly strong hydropower generation potential that remains underutilised.

Parallel markets Much has been made about the apparent disconnect between the current global oil surplus on the one hand and inventories near decade lows at key pricing hubs on the other. Indeed, despite record volumes of oil piling up on water, benchmark crude oil prices eased only marginally in November, with North Sea Dated last trading at around $63/bbl and WTI at $59/bbl, with lower forward disincentivizing storage. Still, the market trends have cle...

De-risking LFP cathode, PPA and manganese sulphate production projects is crucial, also reducing domestic equipment and machinery costs, as well as providing demand incentives for domestic production. Sodium-ion presents a potential supply security opportunity due to its more diversified upstream supply chain, with the United States and Europe already playing key roles in soda ash, caustic soda and biomass supply. Yet, the downstream supply chain – cell, cathode and hard carbon anode – remains dominated...

Transport accounts for around 30% of global energy demand and have contributed around 10% of the growth in total demand since 2019. Road transport accounts for nearly 90% of total domestic energy demand. The remaining 10% is split between domestic aviation, domestic shipping and rail.In advanced economies, passenger cars dominate road transport demand, accounting for around 65% of the transport energy use. Trucks make up most of the remainder. Buses play a minor role in energy demand…

                Energy Efficiency Policy Toolkit AppliancesAppliances

                Introduction Appliances represent 45% of electricity demand in buildings and are responsible for almost 3 gigatons (Gt) of CO₂ emissions. Doubling the global annual energy intensity improvement by 2030 would require appliances to become 30% to 40% more efficient. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal. Regulations such as minimum energy performance standards (MEPS) can ensure that the least efficient equipment is not sold on the market. MEPS also encourage suppliers to increase the efficiency of the appliances they produce, accelerating the improvement of efficiency on the market. In…

Around USD 2.2 trillion is going collectively to renewables, nuclear, grids, storage, low-emissions fuels, efficiency and electrification, twice as much as the USD 1.1 trillion going to oil, natural gas and coal.
