Green Energy Consumer Statistics: Public Demand for Renewable Energy
Pew Research Center surveyed 10,329 U.S. adults using a weighted online panel from May 30-June 4, 2023. These are stated opinions, not purchases, measured energy use or observed changes in the energy mix.
| Survey measure | Share of U.S. adults | Period |
|---|---|---|
| Support international climate efforts | 74% | May 30-June 4, 2023 |
| Prioritize alternative energy over more fossil-fuel production | 67% | May 30-June 4, 2023 |
| Require power plants to eliminate carbon emissions by 2040 | 61% | May 30-June 4, 2023 |
| Phase out gas-powered cars and trucks | 40% | May 30-June 4, 2023 |
| Require most new buildings to use electricity without gas lines | 46% | May 30-June 4, 2023 |

Views on fossil fuels were more divided. In the same survey, 31% supported phasing out fossil-fuel energy altogether, 32% said the United States should eventually stop using fossil fuels but was not ready then, and 35% said it should never stop using them for energy needs.
The building measure was also closely divided: 46% favored requiring most new buildings to run only on electricity with no gas lines, while 51% opposed it. The opposing categories do not include nonresponse, and the result measures policy opinion rather than the building stock.
The survey also recorded climate-related experiences. During the prior year, 69% reported at least one of five specified extreme-weather types, including 45% who reported long periods of unusually hot weather and 44% who reported severe weather such as floods or intense storms.
Residential Solar Adoption and Generation Trends
The U.S. Energy Information Administration reports an estimated series for residential small-scale solar PV generation. The series uses EIA-861M and EIA-861 data plus estimation methods, so it measures generation in the U.S. residential sector rather than the number of households with panels.
| Year | Residential small-scale solar PV generation |
|---|---|
| 2014 | 4,947 thousand MWh |
| 2015 | 6,999 thousand MWh |
| 2016 | 10,595 thousand MWh |
| 2017 | 13,942 thousand MWh |
| 2018 | 17,105 thousand MWh |
| 2019 | 20,914 thousand MWh |
| 2020 | 25,179 thousand MWh |
| 2021 | 30,182 thousand MWh |
| 2022 | 39,510 thousand MWh |
| 2023 | 49,273 thousand MWh |
| 2024 | 57,547 thousand MWh |
Source: Table 3.6. Net Generation by Energy Source: Residential Sector, 2014-2024.
The reported generation series rises from 4,947 thousand MWh in 2014 to 57,547 thousand MWh in 2024. The figures are EIA estimates, and the 2024 note says totals may differ from component sums because of independent rounding.
Generation is not the same as adoption. A household can participate through an owned system, a leased system, a community arrangement or purchased electricity, while this table records estimated output from small-scale residential PV.
Consumer Solar-Plus-Storage and Distributed-Energy Data
California provides a detailed view of battery pairing, but the observations are not a national household-adoption rate. EIA defines small-scale systems as under 1 MW and notes that about 99.5% of California small-scale residential capacity was net metered.
| California measure | Reported figure | Period or comparison |
|---|---|---|
| Residential net-metered solar capacity | More than 12,000 MW | March 2024 context |
| New residential PV paired with batteries | Just over 20% | October 2023 |
| New residential PV paired with batteries | More than 50% | April 2024 |
| Solar-plus-battery share of residential net-metering capacity | About 9% | April 2024 context |
| Added solar-plus-battery installations | More than 40,000 | October 2023-April 2024 |
| New battery-storage capacity in those additions | 232 MW | October 2023-April 2024 |
Source: California residents are increasingly pairing battery storage with solar installations.
The battery-pairing share applies to new installations, not all existing systems. The October 2023-April 2024 installation and capacity figures are based on preliminary EIA data, so they should be read as estimates rather than a final census.
California residential net-metered solar capacity increased 22% in the third quarter of 2023 compared with the same quarter of 2022. EIA noted that capacity growth slowed after a change in the compensation structure, but the surrounding estimates remain a capacity measure rather than a direct measure of consumer bills or household savings.
Global Green Energy Market Growth Affecting Consumers
Worldwide capacity additions show the scale of the supply transition that shapes consumer choice, equipment availability and distributed-energy markets. IEA 2024 figures combine actual and estimated additions where stated, and national totals include utility-scale as well as distributed projects unless a narrower definition is specified.
| Market or measure | 2024 figure | Definition |
|---|---|---|
| Global renewable-capacity additions | About 700 GW | Estimated annual additions, up 25% |
| Global solar PV additions | About 550 GW | Almost 30% year over year |
| Installed solar PV worldwide | Estimated 2.2 TW | Global stock |
| China solar PV additions | More than 340 GW | 30% above 2023; DC capacity |
| China residential PV installations | 30 GW | Less than 10% of China’s solar additions |
| European Union solar PV additions | Around 60 GW | More than twice 2021 annual additions |
| U.S. solar PV additions | Almost 50 GW | National total |
| India solar PV additions | Around 30 GW | Almost triple 2023 growth |
| Brazil solar PV additions | More than 16.5 GW | National total |

Solar PV made up more than three-quarters of 2024 renewable-capacity additions, while solar PV and wind together represented 95% of overall renewable-capacity growth. China connected almost two-thirds of all renewable capacity added to grids worldwide in 2024.
The China residential figure is narrower than the national total: 30 GW of residential PV was less than 10% of China’s solar additions. Similarly, the U.S., European Union, India and Brazil figures include non-residential projects, so they are market-scale indicators rather than household adoption rates.
IEA’s main case forecasts annual renewable-capacity additions rising from 666 GW in 2024 to almost 935 GW in 2030. Solar PV and wind are forecast to account for 95% of additions through 2030, distributed applications for almost 40% of PV expansion, and total global renewable capacity for almost 9,760 GW in 2030, or 2.7 times 2022 capacity.

Heat-Pump Adoption and Renewable Home-Heating Statistics
Heat-pump statistics use several denominators. A share of heating needs is an energy-service measure, a sales share describes new equipment purchases, and manufacturing capacity describes production potential rather than installed units.
In 2024, heat pumps supplied around 5% of global heating needs and around 12% of global building-space-heating needs. They also represented between 2% and 16% of annual peak electricity demand across major markets, with the range varying by climate and adoption.
More than 70% of building-sector heat-pump sales in all major markets were sourced domestically in 2024. Global heat-pump manufacturing capacity was roughly 145 GW per year, and global heat-pump-sector employment had risen around 50% since 2015.

| Heat-pump market measure | Figure | Period and geography |
|---|---|---|
| European purchases | 6.5% lower year over year | Europe, 2023 |
| Share of heating-system sales | Almost one-third | Europe, 2023 |
| Heat-pump market growth | 12% | China, 2023 |
| Newly installed global capacity | 3% lower than 2022 | World, 2023 |
Source: Renewables 2024: Global overview.
European purchases contracted 6.5% year over year in 2023, even though heat pumps represented almost one-third of heating-system sales. China’s market grew 12%, while newly installed global heat-pump capacity was 3% lower than in 2022; these are market measures, not household stock estimates.
Consumer Barriers, Affordability and the Green Energy Outlook
The available outlook measures global energy consumption and emissions rather than the price paid by an individual household. IEA’s main-case forecast projects global renewable-energy consumption rising nearly 60% from 2024 to 2030, lifting renewables from 13% of final energy consumption in 2023 to nearly 20% in 2030.
Renewable heat consumption is forecast to grow more than 50%, or 15 EJ, during 2024-2030. That definition includes bioenergy, solar thermal, geothermal, ambient heat from heat pumps and indirect renewable electricity; industry ambient heat is excluded because of limited data.
The forecast increase in renewable heat during 2024-2030 is 2.4 times the increase during the previous six-year period. Even so, annual heat-related CO2 emissions are forecast to climb 4% by 2030 because renewable heat growth remains below total heat-demand growth.
Cumulative heat-related emissions during 2024-2030 are forecast to exceed 100 Gt CO2. These are scenario results dependent on carbon-budget and non-CO2 mitigation assumptions, not measured future outcomes.

For consumers, the central distinction is between willingness, participation and outcome. Survey support can indicate demand for change, residential generation and storage show specific forms of participation, sales reveal equipment-market movement, and forecasts describe a policy- and infrastructure-dependent pathway rather than a guaranteed household result.
