The Decarbonization Market is being transformed by the rapid expansion of renewable energy, which is now the cheapest source of new electricity generation in most parts of the world. Solar PV costs have fallen by 85% since 2010, onshore wind costs by 50%, and offshore wind costs by 60%, making renewables economically competitive with fossil fuels without subsidies in many regions. Solar PV capacity has grown from 40 GW in 2010 to over 1,000 GW in 2023, with China, the US, India, Japan, Germany, Brazil, Australia, Spain, Italy, France, Netherlands, South Korea, Vietnam, and Australia leading deployment. Wind capacity has grown from 200 GW to over 900 GW, with China, the US, Germany, India, Spain, UK, France, Brazil, Canada, Sweden, Turkey, Poland, Netherlands, and Australia leading. Hydropower remains the largest source of renewable electricity (over 1,300 GW), with China, Brazil, Canada, the US, India, Russia, Norway, Japan, Turkey, and France leading. Geothermal, tidal, wave, and biomass provide smaller but growing contributions. The integration of renewables into electricity grids requires investment in transmission infrastructure (high-voltage lines, substations, transformers, interconnectors), energy storage, and demand-side management.
Decarbonization Market was valued at USD 1.9 Billion in 2023 and is projected to grow to USD 6.17 Billion by 2033, with a compound annual growth rate (CAGR) of 12.5% from 2027 to 2033. Renewables now account for over 30% of global electricity generation, with the International Energy Agency (IEA) projecting that share to reach 50% by 2030. Solar PV is the fastest-growing source, with annual additions of over 200 GW in recent years, driven by falling module prices (now under $0.20 per watt), improved efficiency (22-25% for monocrystalline, 20-22% for polycrystalline, 18-20% for thin-film), and innovative mounting systems (fixed tilt, single-axis tracking, dual-axis tracking, floating solar, agrivoltaics, building-integrated photovoltaics (BIPV), vehicle-integrated photovoltaics (VIPV), solar canopies, solar carports, solar facades, solar roofs, solar windows). Wind energy is also growing rapidly, with larger turbines (5-15 MW for onshore, 10-20 MW for offshore), taller towers (100-200 meters), and longer blades (50-100 meters) enabling capture of stronger, more consistent winds at higher altitudes.
