Solar is now ‘cheapest electricity in history’

solar

There is some very good solar energy news. About this time of year, each and every year, the International Energy Agency’s (IEA) World Energy Outlook is published, and the 2020 edition is now available. What it reveals about solar is very encouraging – solar projects now offer some of the lowest cost electricity ever seen.

Published 13 Oct, this latest 464-page edition contains all the details.

It has a very strong COVID-19 Focus

The Covid-19 crisis has caused more disruption than any other event in recent history, leaving scars that will last for years to come. But whether this upheaval ultimately helps or hinders efforts to accelerate clean energy transitions and reach international energy and climate goals will depend on how governments respond to today’s challenges.

This new 2020 edition focuses on the pivotal period of the next 10 years, exploring different pathways out of the crisis. The new report provides the latest IEA analysis of the pandemic’s impact: …

  • global energy demand is set to drop by 5% in 2020
  • energy-related CO2 emissions is set to drop by 7%
  • energy investment is set to drop by 18%.

Beyond what has happened, they are comparing different scenarios that show how the energy sector could develop.

Solar

Renewables take starring roles in all their scenarios, with solar centre stage. Supportive policies and maturing technologies are enabling very cheap access to capital in leading markets. Solar PV is now consistently cheaper than new coal- or gas-fired power plants in most countries, and solar projects now offer some of the lowest cost electricity ever seen. In the Stated Policies Scenario, renewables meet 80% of global electricity demand growth over the next decade. Hydropower remains the largest renewable source, but solar is the main source of growth, followed by onshore and offshore wind.

“I see solar becoming the new king of the world’s electricity markets. Based on today’s policy. If governments and investors step up their clean energy efforts in line with our Sustainable Development Scenario, the growth of both solar and wind would be even more spectacular – and hugely encouraging for overcoming the world’s climate challenge.”

Dr Fatih Birol, the IEA Executive Director.

It is not all magic, there must be infrastructure investment

The WEO-2020 shows that strong growth of renewables needs to be paired with robust investment in electricity grids. Without enough investment, grids will prove to be a weak link in the transformation of the power sector, with implications for the reliability and security of electricity supply. 

Fossil fuels face varying challenges. Coal demand does not return to pre-crisis levels in the Stated Policies Scenario, with its share in the 2040 energy mix falling below 20% for the first time since the Industrial Revolution. But demand for natural gas grows significantly, mainly in Asia, while oil remains vulnerable to the major economic uncertainties resulting from the pandemic.

“The era of global oil demand growth will come to an end in the next decade,” Dr Birol said. “But without a large shift in government policies, there is no sign of a rapid decline. Based on today’s policy settings, a global economic rebound would soon push oil demand back to pre-crisis levels.”

The worst effects of the crisis are felt among the most vulnerable. The pandemic has reversed several years of declines in the number of people in Sub-Saharan Africa without access to electricity. And a rise in poverty levels may have made basic electricity services unaffordable for more than 100 million people worldwide who had electricity connections.

What will happen in the Post-COVID-19 world?

Global emissions are set to bounce back more slowly than after the financial crisis of 2008-2009, but the world is still a long way from a sustainable recovery. A step-change in clean energy investment offers a way to boost economic growth, create jobs and reduce emissions. This approach has not yet featured prominently in plans proposed to date, except in the European Union, the United Kingdom, Canada, Korea, New Zealand and a handful of other countries.

In the Sustainable Development Scenario, which shows how to put the world on track to achieving sustainable energy objectives in full, the complete implementation of the IEA Sustainable Recovery Plan moves the global energy economy onto a different post-crisis path. As well as rapid growth of solar, wind and energy efficiency technologies, the next 10 years would see a major scaling up of hydrogen and carbon capture, utilisation and storage, and new momentum behind nuclear power.

“Despite a record drop in global emissions this year, the world is far from doing enough to put them into decisive decline. The economic downturn has temporarily suppressed emissions, but low economic growth is not a low-emissions strategy – it is a strategy that would only serve to further impoverish the world’s most vulnerable populations,” said Dr Birol. “Only faster structural changes to the way we produce and consume energy can break the emissions trend for good. Governments have the capacity and the responsibility to take decisive actions to accelerate clean energy transitions and put the world on a path to reaching our climate goals, including net-zero emissions.”

Getting to Net-Zero CO2

A significant part of the efforts would have to focus on reducing emissions from existing energy infrastructure – such as coal plants, steel mills and cement factories. Otherwise, international climate goals will be pushed out of reach, regardless of actions in other areas. Detailed new analysis in the WEO-2020 shows that if today’s energy infrastructure continues to operate in the same way as it has done so far, it would already lock in a temperature rise of 1.65 °C. 

Despite such major challenges, the vision of a net-zero emissions world is increasingly coming into focus. The ambitious pathway mapped out in the Sustainable Development Scenario relies on countries and companies hitting their announced net-zero emissions targets on time and in full, bringing the entire world to net zero by 2070.

Reaching that point two decades earlier, as in the new Net Zero Emissions by 2050 case, would demand a set of dramatic additional actions over the next 10 years. Bringing about a 40% reduction in emissions by 2030 requires, for example, that low-emissions sources provide nearly 75% of global electricity generation in 2030, up from less than 40% in 2019 – and that more than 50% of passenger cars sold worldwide in 2030 are electric, up from 2.5% in 2019. Electrification, innovation, behaviour changes and massive efficiency gains would all play roles. No part of the energy economy could lag behind, as it is unlikely that another would be able to move fast enough to make up the difference.
