This article is for those who want to understand the importance of timing: when is the right time to impose new standards and start/stop subsidies, to optimise the pathway to maximum efficiency? The light bulb transition of the last two decades is one of the successes of energy efficiency: from the old incandescents (15 lumens/watt) to halogen incandescents and CFLs, and then, finally, to LEDs (80 lumens/watt and prices falling 90% in ten years). … [Read more...]
Biomethane for decarbonising transport: the Swedish example
Biomethane has a critical role to play in the decarbonisation of transport, particularly long-distance trucks and ships, where electrification is more difficult and expensive. Angela Sainz Arnau at the European Biogas Association explains that biomethane represents one of the lowest greenhouse gas intensive pathways when the whole emissions lifecycle is measured. However, when nations implement bans on internal combustion engines to cut the use … [Read more...]
Smart households in a high Renewables world: flexible, efficient, cheaper
Smart controls can enable household heating and EVs to interact flexibly with increasingly decentralised electricity generation. As renewables continue to be added to the energy mix, it will increase efficiency, reduce load, and save money. Marco Reiser and Karoline Steinbacher at Guidehouse summarise the challenges and opportunities, before looking at the SINTEG pilot in Germany. The main hurdles are technological (standardisation, interfaces, … [Read more...]
Appliances and Equipment Efficiency Standards: energy savings rival total Wind & Solar generation
Don’t underestimate the effect of Energy Efficiency Standards and Labelling (EES&L) programmes for appliances and equipment, says the IEA. In other words, the gradual tightening of efficiency rules for things like refrigerators, ACs, TVs, washing machines, cookers, vending machines and other electronics. In the nine countries and regions measured (including the U.S., the EU and China), EES&L programmes reduced electricity consumption by … [Read more...]
The U.S. now needs a Carbon Tax to transition from Gas to Renewables
Gas emissions must be halved (and coal eliminated) by 2030 to meet President Biden’s goal of a carbon free power sector by 2035. The problem is that gas additions are half the price of new wind and solar installations. Though the clean energy champions are still getting cheaper, so are gas additions. Nikos Tsafos at the Center for Strategic and International Studies looks at the policy options over the next decade for the U.S. The stark fact is … [Read more...]
Green Finance standards: the EU Taxonomy and China’s “Catalogue”
The EU Taxonomy was published in June 2020. It is the first official document to define and classify what is a truly sustainable economic activity in Europe. Six months later China’s regulators published their own version, a new edition of the China Green Bond Endorsed Project Catalogue (the Catalogue). Both documents will act as important standards for green finance institutions and investors in Europe and China. They are intended to improve … [Read more...]
CBAM needs universal adoption of methods for measuring carbon intensity
Europe needs to account for the emissions of imported goods. That cannot happen without the international agreement on standards and certification systems for the carbon intensity of all steps in the value chain for all relevant products. Dolf Gielen and Francisco Boshell at IRENA and Massamba Thioye at the UNFCCC explain that several such systems exist around the world, but they need to be harmonised and widely adopted to truly reflect what is … [Read more...]
Super-efficient space cooling can mitigate 0.5°C of warming by 2100
Space cooling eats up 10% of global electricity use, and by 2050 total energy consumed could triple as ownership takes off in developing countries. It’s why the Global Cooling Prize was launched to find AC designs that will have an 80% lower climate impact, explains John Matson at RMI. The two main design goals were to reduce electricity demand, and use refrigerants with lower global warming potential (GWP) than traditional refrigerant gases. The … [Read more...]
How Clean Energy Standards have driven clean electrification in the U.S.
John Rogers at the Union of Concerned Scientists presents evidence from the U.S. of the effectiveness of using standards to drive clean electrification. In principle it’s simple: set a legal requirement for the percentage of clean electricity. How it’s done depends on the efforts of all the actors affected. 30 states are using different versions of Clean Energy Standards (CES) – the first began in 1983 and more than half of them began before 2004 … [Read more...]
Saudi Arabia’s clean hydrogen plans for converting ambitions into action
The recent Memorandum of Understanding with Germany on clean hydrogen cooperation underlines Saudi Arabia’s ambition in becoming a global powerhouse producer in this field. Governments and industry players are currently considering clean hydrogen as an energy vector with key energy transition roles in an increasingly carbon-constrained world. Hydrogen has the potential to grow into a trillion-dollar commodity market, with enormous opportunities … [Read more...]
Climate Neutral Cities can be the key to winning public support for the European Green Deal
The EC is currently considering a mission proposal to achieve “100 climate neutral cities by 2030 – by and for the citizens”. Arguing for its endorsement and the proposed umbrella governance, Simon Skillings and Eleonora Moro at E3G explain why cities are an ideal laboratory for tackling the big unanswered question: which European Green Deal (EGD) pathways will win genuine public support. No one should doubt that the EGD will be disruptive. So … [Read more...]
Are Regulations and Climate Activism the main driver for coal exits, not Gas and Renewables prices?
It’s widely thought in the media and politics that market forces are now the primary driver for the demise of coal: mainly natural gas prices, and the rising adoption and competitiveness of wind and solar. However, David Drake and Jeffrey York at the University of Colorado Boulder present their research from the U.S. that suggests the two main drivers are federal policy and climate activism. They studied the retirement of 348 coal-fired units … [Read more...]
EU Taxonomy: 5 principles for avoiding unintended consequences
The EU Taxonomy is a classification system that defines a list of environmentally sustainable economic activities. If your activity is on the list you should see green finance flow your way. Hence the heated debate over what is “green”. It’s of vital interest to sectors like gas and nuclear (it’s green compared to the coal it replaces) as it will have a major effect on the cost of capital and therefore the future of the sector. Indeed, any … [Read more...]
E-mobility in Germany: a record year but still way off target
In the past few months Germany has seen record levels for electric car registrations. But will this rising trend be enough to meet the government’s target of 10 million electric cars by 2030? To answer the question Naemi Schink and Simon Göss at Energy Brainpool look at the data, proposed new regulations, and funding. Though the number of electric cars has grown by over 360% in the last year there are currently only 240,000 EVs and 200,000 … [Read more...]
