Sustainable energy source -
Prices for renewable energy technologies are dropping rapidly. The cost of electricity from solar power fell by 85 percent between and Costs of onshore and offshore wind energy fell by 56 percent and 48 percent respectively. Falling prices make renewable energy more attractive all around — including to low- and middle-income countries, where most of the additional demand for new electricity will come from.
With falling costs, there is a real opportunity for much of the new power supply over the coming years to be provided by low-carbon sources. It could decarbonize 90 percent of the power sector by , massively cutting carbon emissions and helping to mitigate climate change.
Although solar and wind power costs are expected to remain higher in and then pre-pandemic levels due to general elevated commodity and freight prices, their competitiveness actually improves due to much sharper increases in gas and coal prices, says the International Energy Agency IEA.
According to the World Health Organization WHO , about 99 percent of people in the world breathe air that exceeds air quality limits and threatens their health, and more than 13 million deaths around the world each year are due to avoidable environmental causes, including air pollution.
The unhealthy levels of fine particulate matter and nitrogen dioxide originate mainly from the burning of fossil fuels. Switching to clean sources of energy, such as wind and solar, thus helps address not only climate change but also air pollution and health.
Every dollar of investment in renewables creates three times more jobs than in the fossil fuel industry. The IEA estimates that the transition towards net-zero emissions will lead to an overall increase in energy sector jobs : while about 5 million jobs in fossil fuel production could be lost by , an estimated 14 million new jobs would be created in clean energy, resulting in a net gain of 9 million jobs.
In addition, energy-related industries would require a further 16 million workers, for instance to take on new roles in manufacturing of electric vehicles and hyper-efficient appliances or in innovative technologies such as hydrogen.
This means that a total of more than 30 million jobs could be created in clean energy, efficiency, and low-emissions technologies by Ensuring a just transition , placing the needs and rights of people at the heart of the energy transition, will be paramount to make sure no one is left behind.
The upfront cost can be daunting for many countries with limited resources, and many will need financial and technical support to make the transition.
But investments in renewable energy will pay off. Moreover, efficient, reliable renewable technologies can create a system less prone to market shocks and improve resilience and energy security by diversifying power supply options.

They offer an alternative to investment in new fossil fuel power generation plants and displace generation from existing units. In the NZE Scenario, renewable power in the form of direct electricity use or indirect use, e. in the form of renewable hydrogen, is expected to displace the majority of fossil fuels use in end-use sectors, especially industry and transport.
Renewable heat sources like modern bioenergy, geothermal plants and solar heaters will also play a major role in decarbonisation of the heating sector. The increase in renewables as a share of energy supply in was the second largest in history, but even faster increases are needed to align with the NZE Scenario.
Modern bioenergy's share in increased by 0. Record renewable electricity capacity additions in , and an increase in hydropower availability, allowed non-bioenergy renewables to achieve their second highest share growth in history. This result is second only to growth in , an unusual year, when the Covid pandemic led to a global economic crisis and resulting decrease in total energy consumption, while use of renewables remained robust.
Despite record renewable electricity capacity additions in , supply growth was still significantly below that level. Much faster deployment of all renewable technologies in all regions of the world will be needed to put the world on track with the NZE Scenario.
Accelerating wind and solar PV capacity additions are driving the growth in renewable energy supply, but activity needs to ramp up rapidly to align with the NZE Scenario. Electricity and heat generation growth in geothermal, concentrated solar power CSP and ocean technologies mostly stalled in due to limited capacity additions.
Solar PV has been the fastest growing technology by capacity additions in recent years and is aligned with the NZE Scenario. In the case of wind, hydropower and bioenergy, more efforts are needed to get on track, as growth in recent years and that expected in the near future is significantly below required levels.
Other less widely used renewable technologies, such as CSP, geothermal and ocean power, are not on track and require a rapid step-up in support.
Positive policy developments in China, the European Union, the United States and India will drive faster renewables growth in the coming years.
Renewable electricity is subject to policy support and national targets in the majority of countries around the world. Various types of support have been implemented, including technology-specific measures. The following important changes have been implemented in the past couple of years:.
The current global energy crisis brings both new opportunities and new challenges for renewable energy. This report forecasts the deployment of renewable energy technologies in electricity, transport and heat to while also exploring key challenges to the industry and identifying barriers to faster growth.
It frames current policy and market dynamics while placing the recent rise in energy prices and energy security challenges in context. Lead authors Piotr Bojek. For all renewable power and heat technologies, long-term targets and policy stability are essential to ensure investor confidence and continued growth.
At the same time, policies need to adapt continuously to changing market conditions to achieve greater cost-competitiveness and to improve the integration of renewables into the energy system.
Achieving a high penetration of renewable power and heat technologies is a necessary condition to decarbonise many carbon-intensive sectors of the economy, including heavy industry, construction and transport.
The expansion of renewable hydrogen use, emissions-free heating in buildings, and electric vehicles requires an integrated approach, connecting the utilisation of all renewable energy technologies. Policy makers should focus on implementing long-term plans for whole-economy decarbonisation and implement incentives reflecting the requirements of all economic sectors.
Policy instruments used to support renewable power include administratively set feed-in tariffs or premiums, renewable portfolio standards, quotas and tradeable green certificate schemes, net metering, tax rebates and capital grants. Recently, auctions for the centralised competitive procurement of renewables have become increasingly widespread and have been instrumental in discovering renewable energy prices and containing policy costs in many countries, especially for solar PV and wind.
The success of such policies in achieving deployment and development objectives relies on their design and consequent ability to attract investment and competition. Increasingly competitive, renewables — especially solar PV and wind — are rapidly transforming power systems worldwide.
However, reforms to power market design and policy frameworks will be needed to ensure investment at scale both in new renewable capacity and in power system flexibility to integrate high shares of variable renewables in a reliable and cost-effective manner.
As the share of variable renewable energy increases, policies ensuring investment in all forms of flexibility become crucial. Solutions include enhancing power plant flexibility, unlocking demand-side management, supporting energy storage and improving grid infrastructure.
Better remuneration of the market value of storage is necessary to accelerate deployment of CSP, pumped-hydro storage and reservoir hydropower technologies.
Timely grid connection and continued implementation of policies that spur competition are needed to achieve further cost reductions in offshore wind. Improving the competitiveness of renewable heating technologies through support policies is necessary to accelerate their deployment.
Lengthy and complicated permitting processes are hampering deployment of new renewable capacity, especially in Europe. Due to complicated requirements, responsibility being split between multiple government agencies and understaffing, the development of renewable energy projects can take up to ten years.
