The anxiety expressed by young people today about Climate Change is reasonable, but they offer no thought-out solution. We should examine the available scientific options in a form accessible to those without specialised knowledge and starting from what natural science has to say about energy and where to find it. (In this article precision is set aside to allow the science underlying the orders of magnitude to be clear and simple.) … [Read more...]
Electricity Capacity Mechanisms face legal challenge in UK, Poland
Recognising that energy markets might not always be able to meet demand on their own, the European Commission allows EU Member States to operate Capacity Mechanisms (CMs). These schemes offer contracts via publicly administered auctions to suppliers who help 'guarantee' there is always spare power for the grid, even as demand and supply fluctuate. But the designs of the CMs are proving contentious, and legal challenges to CMs threaten to shut … [Read more...]
IEA: Global energy investment stabilises at $1.8tn after 3 years of decline
Three consecutive years of declining global energy investment has ended. But it’s not risen, just stabilised at $1.8tn, according to the IEA’s latest report World Energy Investment 2019. To meet the Paris targets investment in efficiency needs to rise substantially, and double by 2030 for renewables: they have stalled for both. To meet soaring global energy demand oil and gas investments need to rise too. That demand is seeing cheap coal still … [Read more...]
IEA: Renewables growth worldwide is stalling
It’s bad enough that 2018 net capacity additions did not exceed 2017’s after two decades of strong growth. It is far more troubling that nobody saw it coming, says the IEA, who have laid out the data and main cause: stop-go policies. 2018's 180 GW is only 60% of what needs to be added each year to meet climate goals. China, the EU, India and Japan all fell back. Only emerging economies, developing countries and the US (slightly) saw growth. … [Read more...]
2009 to 2017: solar, wind costs plummet, hydro steady, nuclear up
Between 2009 and 2017 prices dropped 76% for solar panels and 34% for wind turbines. Hydro and nuclear struggle to cut costs; as mature technologies, most of the efficiencies have already been squeezed out already. Also, they are difficult to productise and scale; dams (definitely) and nuclear plants (somewhat) are one-offs. In contrast, solar panels and wind turbines are far easier to productise and then mass produce. It’s why wind overtook … [Read more...]
There’s a limit to raising CO2 taxes. Re-focus on energy innovations to reverse emissions
Stop obsessing about raising CO2 taxes, says Severin Borenstein at the Energy Institute at Haas. It’s good, but not enough. Why? Textbook economics says if you tax something bad, innovators are incentivised and rewarded for coming up with something better. That’s true for cigarettes (vaping), plastic wrapping (recyclables, biodegradables), traffic (public transport). But there’s a limit with CO2 taxes, says the author. In developing countries … [Read more...]
Leaked German govt report: emissions target will be missed despite on-target renewables
A leaked draft of Germany’s Energiewende Progress Report 2019, due to be released by the economy ministry in May or June, predicts the country will miss its targets for reducing energy use and greenhouse gas emissions by wide margins. This is despite the inevitable emissions reductions due to the 2009 recession and being on track for renewables. If no other measures are taken Germany will reduce emissions by 33% by 2020, falling short of the … [Read more...]
From rooftop solar to carbon divestment, California leads the transition
California doesn’t wait for Washington. As America’s most populous state by far, it is behaving like a separate nation when it comes to climate policies. Tim Buckley, Director of Energy Finance Studies at IEEFA Australasia, says it has become a global leader in renewable energy. Renewables provided 34% of its total energy needs in 2018, and the business community sees economic success in further progress. The author runs through the highlights, … [Read more...]
PPA 2.0: future-proofing corporate energy funding
Power purchase agreements (PPAs) are a significant tool for funding the energy transition. Research by DNV GL suggests that, as renewable energy becomes more widespread, its price dynamics becomes more complex, and that matters to PPAs. Some governments are looking to phase out subsidies and feed-in tariffs, effectively softening their price guarantees. Also, as renewables generation grows, market prices can fall. Martijn Duvoort, Director Energy … [Read more...]
UK: Despite progress, 100% low-carbon is still a long way off
The UK transition is often cited as a success story. Coal’s contribution has dropped from 40% to 6%. Wind, solar and hydroelectric now generates more electricity than nuclear. Demand for electricity has also fallen. The carbon intensity of Britain’s electricity has almost halved, from over 500g of CO₂ per kilowatt-hour in 2006 to under 270g in 2018. The National Grid now expects to be able to operate a zero-carbon electricity system by 2025. But … [Read more...]
“Responsible” ESG investments hit $20tn, a quarter of the world’s professionally managed total
ESG (Environmental, Social and Governance) factors measure the sustainability and ethical impact of an investment. ESG includes the energy sector, and the amounts spent show it’s no longer just an ethical choice, says The Rocky Mountain Institute’s Todd Zeranski. It doesn’t just save the planet, it saves our pensions. Why? From regulatory penalties to the cost of climate clean-up, fossil fuel investments are getting too risky and expensive. Those … [Read more...]
“Stop trading renewable energy supply certificates, speed up the transition”
In the UK, REGOs certify that the power a consumer buys is renewable. As REGOs can be traded that means one supplier, sourcing 100% of their energy from renewables, and another simply buying enough REGOs to cover 100% of their output can both say they are 100% renewable. Is there a difference? Yes, says Thomas Harrison at supplier Good Energy. Trading REGOs takes the pressure off suppliers to use all their buying power to expand the supply of … [Read more...]
NECPs – Analysis: EU ideals coming up against political realities
The European Union is trying to maintain its leadership on climate change with its Clean Energy for All Europeans package, which aims to make the EU climate neutral by 2050. The mechanism for achieving this target is member states’ National Energy and Climate Plans (NECPs). Mike Scott considers the plans, how Germany is moving towards an "Eastern European" energy policy and how the upcoming elections could dilute EU climate policy overall... … [Read more...]
New “Gas for Climate” scenarios: can green gas and hydrogen save gas pipelines?
Gas has a key role to play in decarbonising the energy sector. Until a comprehensive clean energy network can accommodate variable renewables using storage, baseload power will be needed. Natural gas is a lower carbon option than coal, so there is a strong case for it to be the first-choice bridging fuel towards a net-zero energy economy. However, exactly how much gas, what type of gas and how existing infrastructure can store energy in the form … [Read more...]
Why does coal survive? A detailed real-world cashflow analysis
Everyone knows coal plants are bad for the environment. So why do countries still use them? Coal’s attractiveness comes from the relatively low up front capital investment required to start generating energy. On top of that, the rapid rise of variable renewables (solar, wind) need something to rise with it to fill the generation gap when the sun doesn’t shine and the wind doesn’t blow. In his final instalment - after his similarly detailed … [Read more...]
