The amount of evidence is rapidly increasing and overwhelming: the era of coal-fired power production is nearly over. Nearly… so let’s explore what is happening and why.
In the US, 74 percent of the existing national coal-fired power generation capacity is currently more expensive than new alternatives, a number that is expected to increase to 86 percent by 2025. The main reasons being low-cost natural gas, the rapidly declining cost of electricity from renewables and the low interest rates for new investments. In total around 19.5 GW of coal capacity has been retired in 2017 and 2018 while only one new 17 MW plant has been built. In Europe 54% of coal capacity currently operating on the EU-28 market is cash flow negative today and this number is expected to increase to 97% by 2030. This is triggered again by declining costs of renewables as well as increasingly stringent environmental policies. Also in less expected areas such as the Gulf Cooperation Council region (GCC), Indonesia, Viet Nam and Philippines the declining renewable energy costs mean that new renewable capacity is cheaper than new coal already today (in GCC) or within a few years, and cheaper than operating existing coal capacity within a decade.
Additionally, capital for coal investment is increasingly harder to get. Multilateral Banks as well as commercial banks and institutional investors are starting to pull out of coal financing. The policy risk of investing in coal is increasing rapidly and shareholders are paying more attention to risks from climate change impacts and policies.
These are encouraging developments. However, there are still several places in the world where new coal investments are taking place or are under consideration. We wondered why these decisions are taken against all odds. The arguments found are diverse and the specific circumstances complex:
- First, politicians often tend to put higher emphasis to the short-term needs of their voters than the longer-term benefits. Short-term jobs in coal mining therewith prevail over the more significant amount of jobs that renewable alternatives bring tomorrow and in the coming decades. Especially in areas with high concentration of coal mining this is a persistent barrier and the challenge of finding alternatives to avoid future stranded regions is highly complicated.
- Second, decoupling of economic development and energy use is often not yet embedded in energy planning. The IEA estimates that by 2040 energy use could almost return to 2017 levels, using cost-effective and currently available technologies, while the global economy could still double over the same time. Nevertheless, security of domestic energy supply still often leads to a perceived need for building high amounts of new, domestic, controllable capacity despite the fact that a growing number of developed and developing economies over the last years have proven that a full decoupling can well be achieved.
- Third, the low cost-effectiveness of coal is not yet observed everywhere right now, especially not where cheap and often carbon intensive coal is abundantly available and the costs of air pollution and greenhouse gas emissions are not yet factored in.
The economics of the modern global energy system and the increasing political momentum to act on climate change make the phase-out of coal-fired power generation inevitable, but the process is complex and could take too long – if not guided by carefully designed policies tailored to the specific context of each country and region. Watch out for a more in-depth analysis on the complex motivations for holding on to coal and possible solutions, which we will publish soon.
Electrification in transport is trendy – but the clear commitment to power it with renewables is still missing
Abating emissions from the transport sector will not be possible without tackling the freight sector
Cities are at the forefront of climate action, as it is where many measures required for decarbonisation in the sector need to be implemented
With mobility being crucial for the economic and social functioning of a society, it is essential to build resilient systems that will continue to function under higher climate change pressures
A lot has happened during the UN climate talks in Glasgow – but are we at all close to the paradigm shift we so urgently need in the transport sector?
Time is Running Out: Carbon Markets Cannot Replace More Ambitious National Commitments — Particularly in Transport
Read our blog after COP25 in Madrid, arguing that we need ambitious commitments for the transport sector. NDC enhancement in 2020 will be crucial.
Ms. Meier is a secretary. She lives and works in a small town in Germany. She has – very likely – never heard of the Paris Agreement, nor would it interest her. Let’s discuss why Ms. Meier is nevertheless key to the success of the Paris Agreement.
The Gambia developed its Intended Nationally Determined Contribution (INDC) for submission to the UNFCCC in advance of the Paris Agreement. Together with Sandra Freitas from Climate Analytics we looked at some initial lessons from the process.
Lima provided another step in the right direction – albeit a baby step, where what we need is a leap. The UNFCCC and the new agreement is just one tool, that needs to be complemented by broader action, including a continuation and strengthening of the divestment movement.
