Image: WIPO 1. Introduction
The Asia-Pacific region consumes nearly half of the world’s energy, over 80% from fossil fuels, driving high greenhouse gas emissions. Rapid population growth and urbanization demand low-carbon solutions like renewable energy, energy efficiency, micro-grids, and agrivoltaics. Innovation in developed and developing countries supports climate adaptation, mitigation, and technology transfer across the region.

Energy technologies are reshaping urban households across Asia-Pacific, addressing challenges from dense living and rising electricity demand. Innovations like rooftop solar, home energy storage, smart appliances, and cool or green roofs help households reduce costs, improve efficiency, lower environmental impacts, and adapt to the region’s intensifying heat due to climate change.

While fossil fuels still dominate Asia’s energy sector, major cities are driving the transition through electric buses, trains, and battery-swapping stations. Innovations in traffic management and redesigned public spaces help reduce energy use, improve air quality, combat urban heat, and enhance overall livability in dense urban environments.

Image: WIPO 2.3 Green urban energy solutions in the Asia-Pacific region - Energy efficiency for water utilities
Water security remains critical, particularly in developing countries, as urban systems demand substantial energy for pumping, purification, and distribution. Advanced solutions like smart metering, energy-efficient infrastructure, and improved management can optimize usage, while innovations in wastewater treatment enable energy recovery, reducing overall consumption and supporting more sustainable urban water systems.

Image: WIPO 3.1 Green rural energy solutions - Climate solutions for rural households and communities
Despite significant electrification progress, roughly 126 million people in the Asia-Pacific region, mainly in rural low-income areas, still lack electricity. Remote terrain, high costs, and regulatory or technical barriers limit access. Emerging solutions such as solar home systems, mini grids, and improved cookstoves are enhancing energy access, resilience, and rural livelihoods.
-
Image: WIPO 3.2 Green rural energy solutions - Clean energy solutions for agriculture on-farm
Energy-efficient technologies are transforming agriculture in rural Asia. Innovations such as solar-powered irrigation and biomass-fueled machinery help farmers reduce reliance on traditional fuels, lower emissions, optimize resources, and enhance productivity, sustainability, and food security in areas with limited energy access.
-
Image: WIPO 3.3 Green rural energy solutions - Clean energy solutions for agriculture post-harvest
Post-harvest agriculture is increasingly benefiting from energy-efficient technologies. Innovations such as solar dryers, efficient milling and processing equipment, energy-saving cold storage, and biogas production from waste help reduce emissions, minimize post-harvest losses, preserve product quality, and extend the shelf life of agricultural products.
-
Image: WIPO 3.4 Green rural energy solutions - Energy transition in fisheries and aquaculture
Small-holder aquaculture is increasingly popular for improving food security and rural incomes but relies heavily on energy, often from fossil fuels. Energy-efficient technologies such as solar-powered fishponds, integrated systems like rice-fish farming, and aquavoltaics are enhancing productivity, sustainability, and resilience for off-grid aquaculture communities.
-
Image: WIPO 4.1 Green energy solutions for key service sectors in the Asia-Pacific region - Low-carbon hotels
The Asia-Pacific hotel industry is a major energy and water consumer, with high emissions per occupied room due to climate and air conditioning needs. Energy-efficient technologies help reduce operational costs and greenhouse gas emissions, but inconsistent data, unclear KPIs, and limited expertise remain challenges to achieving carbon neutrality.
-
Image: WIPO 4.2 Green energy solutions for key service sectors in the Asia-Pacific region - Energy-efficient shopping malls
Shopping malls in Asia are highly energy-intensive due to large spaces, high foot traffic, and integration with offices, hotels, and residences. Energy-efficient technologies such as LED lighting, smart HVAC, CO2 refrigeration, and rooftop solar help reduce costs, lower environmental impact, and support decentralized energy systems.
