A major part of achieving net-zero before 2050 is being able to decarbonize power generation – and make the transition to 100% clean, affordable and reliable energy.

Why? Because emissions from fossil-fuel power generation account for 31% of greenhouse gas emissions (GHG).

This transition has started – and is happening at pace. Over 100 cities around the world are now getting at least 70% of their electricity from renewable sources such as hydro, geothermal, solar and wind. A surge in demand for clean energy – from companies, governments, cities and citizens – is being met with a sea-change in the market competitiveness of wind and solar power, coupled with electricity storage solutions and other key technological innovations.

We have all the technologies available today – particularly in renewables – we simply need to scale them faster. This transition ensures that rapidly growing demand for electricity – driven by the switch to electric vehicles and the increased electrification of industrial processes such as steel making – is met with clean energy.

The pathway is clear: by 2030, 65% of total global electricity consumption should be from renewable sources, and by 2050 or sooner 100% of electricity should be from zero-carbon sources.

But to achieve this, we need to do more, be more ambitious and make changes more quickly.

The good news is rapidly declining prices have seen renewables become cheaper than grid electricity in key markets including China and the US, as renewable energy grows into an increasingly unsubsidized power source.

Global solar capacity grew faster than all fossil fuels combined, including coal, oil and gas-fired power stations, for the first time in 2017. And renewables accounted for almost two-thirds of net new power capacity around the world in 2016.

The signals of change we see today show that – if the rate of change continues, if we continue to do more, faster, we can achieve a fully decarbonized energy system around the world sooner than 2050.

Subsidy-free clean power

Renewable energy is now frequently cheaper than coal or gas – even without subsidies. That’s the finding of a report from the International Renewable Energy Agency (IRENA).

image description

Solar sees remarkable cost decline

The cost of renewables has seen a remarkable drop – electricity from utility-scale solar PV fell 73% between 2010-2017. Solar is now ‘cheaper than grid electricity’ in every Chinese city, one study finds.

image description

The market takes over

When unsubsidized renewables have matured to the point where they are cheaper than fossil fuel power, the transition to a net-zero carbon power system is accelerated by market forces. No longer is the argument philosophical, it is driven by economics.

Clean energy investment is booming

Global investment in new renewables capacity reached $35 billion in the first half of 2020, up 319% year-on-year to surpass the full-year 2019 record figure of $31.9 billion, defying the COVID-19 recession, according to Bloomberg’s New Energy Finance.

+40 power utilities commit to action

Globally, over 40 power utilities have committed to bold climate action, with over 20 companies committing to set science-based targets. A growing number of these have committed to set targets to reach net-zero emissions by 2050, including Ørsted, Iberdrola and NRG Energy.

Ørsted raises the bar for clean energy

In Europe, Ørsted transformed its entire business model to become a clean energy company and is now committed to becoming a carbon neutrality company by 2025 and achieving a carbon neutral footprint by 2040, by working with its suppliers to cut emissions.

Iberdrola ahead of the renewable curve

Iberdola Group has invested €100 billion in the energy transition over the past 20 years, making the Spanish utility a world leader in renewable energy, and is committed to investing many billions more. At year-end 2019, Iberdrola had 52,082 MW of installed capacity, and is expecting to reach 58,000 MW in the coming years.

Tata Power stops building coal plants

In India, Tata Power, India’s largest private integrated power company, is to cease building new coal-based generation projects, shifting to renewable power sources. Simultaneously, a quarter of planned coal-fired power stations were canceled in India in the first half of 2018.

Polish utility focuses on renewables

Poland’s state-run utility Tauron plans to replace most of its coal-burning power plants with renewable sources in the coming decade to adjust to EU climate policies and secure future financing.

Capacity additions dominated by renewables

In 2019, renewables accounted for 41 percent of the rise in energy demand, the largest of any energy source, even out competing natural gas, according to the BP Statistical Review of World Energy. Meanwhile, the BP Energy Outlook predicted that renewables would remain the fastest-growing energy sources over the next three decades.

More countries are setting out pathways to be 100% renewable by 2050 – assisted by researchers at Stanford University, who have plotted out clear roadmaps for 139 nations to transition to 100% renewables by 2050.

image description

India set to exceed renewable targets

India is increasing its target for renewable energy capacity to 227 GW by 2022 because the country is well on its way to exceeding its previous target of 175 GW. This would be nearly three times the 77.5 GW installed renewable capacity in 2018.

image description

Powering Past Coal Alliance

More than 30 countries, including the UK, Canada, France, Finland and Mexico are part of the Powering Past Coal Alliance, committing to phase out existing coal-fired power stations and place a moratorium on new ones. Over 40 organisations and nearly 30 sub-national governments have also joined the alliance.

image description

States step up in renewable switch

In the United States, 13 states, districts and territories, as well as more than 200 cities and counties, have committed to a 100 percent clean electricity target — and dozens of cities have already hit it, according to a report from the UCLA Luskin Center for Innovation. The states that have legislated their renewable electricity targets include – California, New York, Hawaii and Nevada.

Germany sets end date for coal phase-out

Germany’s coal exit commission has agreed that the country should end coal-fired power generation by 2038, with an option to end it by 2035.

image description

Rising public awareness

Climate Strikes, radical activism, public opinion, TV & film and social media all demonstrate feelings of impotence and anger at the slow speed of change. For many citizens, it’s personal because they are concerned for their own health. Pollution from coal-fired power-stations and car exhaust pollution – is literally killing people.

image description

Health problems linked to coal power

Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other severe environmental and public health impacts, according to the Union of Concerned Scientists.

China suffers ‘airpocalypse’

In 2012, more than 1 million people reportedly died from air pollution in China. When a thick smog gripped the country in January 2013, the air pollution was so bad it was called an “airpocalypse”.

image description

The impact of deteriorating air quality

Arvind Kumar, a chest surgeon at New Delhi’s Sir Ganga Ram Hospital, has a ringside view of the toll that northern India’s deteriorating air quality is taking on its residents. When he started practicing 30 years ago, some 80 to 90% of his lung cancer patients were smokers. But in the past six years, half of Dr Kumar’s lung cancer patients have been non-smokers.

image description

Citizens bear the impact

To Dr Kumar, the dramatic shift in the profiles of lung cancer patients has a clear cause: air fouled by dirty diesel exhaust fumes, construction dust, rising industrial emissions and crop burning, which has created heavy loads of harmful pollutants in the air.

image description

Citizens back the clean-energy transition

Air quality is one of the biggest drivers of cultural urgency to make the transition to clean energy. Citizens around the world are embracing renewables as a route to clean air and tackling climate change. Countless public surveys show strong backing for a rapid shift to renewables and opposition to fossil fuels.

Responding to employment challenges

There are very valid concerns about jobs as we rapidly shift from fossil fuel based power generation. Some of these can be allayed by the employment opportunities created up and down the supply chain by the widespread adoption of renewable energy. Worldwide, the sector employed 11 million people in 2018, up from 10.3 million in 2017, according to IRENA.

Subsidy concerns can be overcome

Renewables’ dependence on subsidies is rapidly diminishing. They are already the cheapest source of electricity in many parts of the world, with global technology costs having fallen to a record low, according to IRENA. Many recent renewable projects have been achieved without subsidies, including a wind farm in the Netherlands and one in Germany. Momentum behind ‘subsidy-free’ renewables is growing and technology costs have fallen dramatically.

Cost concerns are easing

The absolute scale of the investment required for energy transitions over 2015-2030 – an additional $300-600 billion annually – does not create a major macroeconomic challenge, but it implies a major shift in investment flows from fossil fuels to low-carbon technologies and energy efficient equipment and infrastructure, according to the ETC.

Reliability can be addressed

Regulators in California are repeatedly choosing renewable energy plus storage over new gas plants, because of voltage regulation advantages as well as cost. In Australia, the Tesla big battery is helping to avoid price spikes and manage power outages rapidly and safely.

Poland engages with labor unions

Poland was forced to face coal restructuring that shrunk employment in the coal mining sector by 75% in only a decade and a half. The government worked with labor unions to develop a mining social package and special privileges for mining communes.

image description

Canada’s just transition task force

A national commitment to phase out coal-fired electricity in Canada was coupled with a national task force made up of industry, labour, environment and coal community representatives. This group travelled across the country to listen to Canadians regarding the support and government policies they need to weather the transition and come out stronger.

image description

Reskilling employees in Australia

ALG Energy’s Liddell coal power station in Australia is re-making itself into a renewable hub, shrinking its overall carbon footprint by 18% and making a 20% reduction in megawatt hour costs. By planning for the transition with its unions, all workers had the option to re-skill or re-deploy, with no forced redundancies.

Change is happening faster than many expect.

The transition to an entirely clean energy power system has begun in earnest. What we are witnessing is a revolution happening right now, with signals of changes all around us. The scale of this transition is often surprising if you don’t see the whole picture.

The benefits will be immense – not only will the transition help address climate change, it will create jobs and sustainable growth, enhance the competitiveness of industry, and protect the health of citizens.

In addition, it will create greater resilience in the economy, increase energy security and dramatically improve people’s quality of life – through better air quality, quieter cities and cleaner energy.

This is the future we want. For ourselves and for future generations.

But even for all these clear signals of change and the momentum achieved, it’s not happening fast enough. Government and business can be more ambitious and speed up the delivery of climate action.

To get to the net zero-carbon economy by 2050, the adoption of climate solutions needs to accelerate to ensure progress happens faster across the entire power system.

We can and we are creating a better future – and it’s our goal to make it happen faster.
