Generation from solar photovoltaics has benefited from government subsidies and the declining cost of panels over the last decade, with capacity increasing from 95 MW in 2010 to 13,800 MW at the end of 2021.
In 2022–23 total electricity generation in Australia increased 1 per cent, to around 274 terawatt hours (988 petajoules), as demand increased across much of the country due to warmer and cooler weather at different points of the year.
In 2028, renewable energy sources account for 42% of global electricity generation, with the wind and solar PV share making up 25%. In 2028, hydropower remains the largest renewable electricity source. However,
Insights Source: National Grid ESO UK electricity generation in 2023 2023 was one of the greenest years on record for electricity generation with the share of renewables on the system continuing to grow. In 2023 more electricity came
Data on renewable power capacity represents the maximum net generating capacity of power plants and other installations that use renewable energy sources to produce electricity. For most countries and technologies, the data
Share of renewables to electricity generated in Japan. The percentage of total electricity generated in Japan are estimated including on-site consumption by power source in 2021 based on Electricity Survey Statistics
In 2023, an estimated 96% of newly installed, utility-scale solar PV and onshore wind capacity had lower generation costs than new coal and natural gas plants. In addition, three-quarters of new wind and solar PV plants offered cheaper
While the contribution of solar energy to global electricity production remains generally low at 3.6%, it has firmly established itself among other renewable energy technologies, comprising nearly 31% of the total installed renewable energy capacity in 2022 (IRENA, 2023).
In 2028, renewable energy sources account for over 42% of global electricity generation, with the share of wind and solar PV doubling to 25%. IEA. Licence: CC BY 4.0 China accounts for almost 60% of new renewable capacity expected to become operational globally by 2028.
Globally, solar PV alone accounted for three-quarters of renewable capacity additions worldwide. Prior to the COP28 climate change conference in Dubai, the International Energy Agency (IEA) urged governments to support five pillars for action by 2030, among them the goal of tripling global renewable power capacity.
Data on renewable power capacity represents the maximum net generating capacity of power plants and other installations that use renewable energy sources to produce electricity. For most countries and technologies, the data reflects the capacity installed and connected at the end of the calendar year.
The share of solar PV and wind in global electricity generation is forecast to double to 25% in 2028 in our main case. This rapid expansion in the next five years will have implications for power systems worldwide.
Reaching an annual solar PV generation level of approximately 8 300 TWh in 2030, in alignment with the Net Zero Scenario, up from the current 1 300 TWh, will require annual average generation growth of around 26% during 2023-2030.
