                As market demand grows, the manufacturing of energy efficiency technologies represents a new opportunity Facing volatile energy prices, rising energy security risks and stricter regulations, all sectors are turning to energy efficiency technologies to reduce consumption and manage these growing challenges. At the same time, governments around the world committed at COP28 in Dubai in 2023 to work collectively to double the global average annual rate of energy efficiency improvements.These dynamics have triggered a strong increase in demand for energy efficiency technologies. For example, the market for electric vehicles (EVs) and batteries has grown nearly six-fold from 2020…

                New Zealand

                New Zealand has a diversified energy mix, with significant production of both hydropower and geothermal. As the country embarks on an ambitious energy transition, it has many natural advantages, including a strong renewable resource base. New Zealand already has a low-emissions electricity system, with over 80% of electricity coming from renewable sources. The key challenge will be to decarbonise other end-use sectors through clean power and support investments in new technologies to achieve deeper emissions cuts across all sectors. Notably, the transport sector accounts for the highest share of emissions and is almost entirely dependent on oil while…

                Recent trends Global investment in manufacturing capacity for six clean energy technologies – solar photovoltaic (PV), wind, batteries, electric vehicles (EVs), electrolysers and heat pumps – dropped below USD 200 billion in 2024, down from nearly USD 220 billion in 2023. This downwards trend is estimated to have continued in 2025, mainly due to weaker solar PV and wind manufacturing investment in China. The United States and the European Union are estimated to have accounted for around 30% of global manufacturing investment combined in 2025, up from 15% in 2023, marginally increasing global supply chain diversification. After dipping in 2024, global trade in clean energy technologies recovered in…

                Southeast Asia becomes one of the main engines of global energy demand growth under today’s policy settings. In the Stated Policies Scenario, the region contributes around 20% of the increase in global energy demand to 2035, supported by sustained economic expansion, rapid electrification and its growing role as a global manufacturing hub. Clean energy expands, but not fast enough to displace fossil fuels. In the STEPS, clean energy meets over 40% of incremental demand growth to 2035, while fossil fuels still meet around 60%. In the Current Policies Scenario, slower policy implementation, financing constraints and power system integration challenges…

This could include, for example, understanding which countries have undeveloped mineral resources that could be mined and refined competitively to satisfy future demand and diversify supply, or the potential to develop a competitive manufacturing base in a particular country to position it in a given clean energy supply chain. To reduce vulnerabilities in the supply chain, better data could help uncover a given country or industry’s exposure to a particular trade partner for a given technology, or to a potential…

                Croatia's National Energy Strategy 2009-2020 has three basic objectives: increase security of energy supply, develop competitive energy system and ensure sustainable energy sector development. These objectives are particularly important for the country, as it is heavily dependent on energy imports, resulting in its vulnerability to energy prices fluctuations.

                GEVO 2026 - Chapter 8 The transition from mechanical to software-based vehicle control has been underway for decades and has accelerated dramatically with the rise of EVs. Pure-play EV makers have pioneered the shift towards high-level, continuously updateable software-based vehicle control, speeding up the development and rollout of new features. Vehicles are evolving into software platforms for which users can access subscription‑based premium features, in the same way as for smartphones. A new design paradigm is emerging, with EVs at the forefront The digital transformation of the car industry is most evident in the emergence of software…

                Slovak Republic

                The key objectives of the Slovak energy policy agenda are: increasing efficiency in the power and end‐use sectors, reducing energy intensity, reducing dependence on energy imports, expanding the use of nuclear power, increasing the share of renewables in the heat and electricity sectors, and supporting the use of alternative fuels for transport. With these sound objectives in place, the government should now focus on the cost‐effective implementation of concrete actions. Mining of coal for electricity production ended in 2023 and an additional nuclear unit was commissioned. The country remains dependent on energy imports from Russia, making energy security…
