In her previous article Sarah Keay-Bright said the outdated Energy Charter Treaty protects old world fossil fuel investments over the wide range of new green investments now being made. The treaty is being reviewed by its signatories this year. In a concluding article, she and Steivan Defilla warn that the terms of reference for the ECT review don’t even mention the need to align the treaty with the Paris Agreement. They say the revised ECT must … [Read more...]
U.S. innovative financing makes buildings energy efficiency affordable even to poor communities
Buildings energy efficiency is not moving fast enough to meet the Paris Agreement goals. Retrofitting old buildings is extremely costly and needs much more investment, as our previous articles have detailed. Innovative models of financing are urgently needed. In an article for Ensia, Nate Berg explains how by rolling upgrade costs into monthly bills for poorer communities, U.S. utilities are helping customers save energy and money at the same … [Read more...]
Climate Auctions can reduce emissions and accelerate regulatory, financial and infrastructure goals
Auctions for delivering an amount of power at a defined price are already well established for renewables. “Climate Auctions” do the same with carbon emissions: a carbon price is guaranteed to the winning bidder, but only paid on delivery of the emissions cut. Tyeler Matsuo and Julia Meisel at Rocky Mountain Institute say this is proving particularly useful in emerging and developing countries where progress in building up their climate laws is … [Read more...]
GGFI: “Avoid carbon bubble, choose financial centre wisely”
We already have indexes that pick green stocks, and rank nations by their policies. The Global Green Finance Index (GGFI) ranks the world’s financial centres – London, New York, Singapore, Shanghai, etc. – by the policies and support they give to green investments. Old ways of valuing assets, particularly in fossil fuel companies, are being questioned say Mike Wardle and Michael Mainelli of the think tank Z/Yen, one of the creators of the index. … [Read more...]
Investing in gas: the effect of carbon taxes, gas prices, and the growth of renewables
Schalk Cloete presents his latest article looking at what affects the profitability of an investment in a specific power sector. After reviewing onshore wind, nuclear and solar, he now looks at gas. His analysis of coal is to come. The major variables are increasing CO2 prices, and natural gas pricing. He adds that the growth of wind and solar should benefit load-following gas power plants: they are plugging the intermittency gap when electricity … [Read more...]
IEA: solar’s exponential growth could make it less competitive, not more
Solar’s current growth trajectory means a doubling of annual deployment every three years. But despite further expected reductions in some cost areas (e.g. cheaper tech and economies of scale), the IEA’s new VALCOE (value-adjusted levelised costs of electricity) metric calculates that solar’s relative competitiveness per unit added will actually decline as its inherent demand-matching issues scale up with the growth. Brent Wanner, WEO Energy … [Read more...]
Africa and renewables: the international partnerships bringing 300GW potential to life
Gaining access to energy is vital for Africa's people and national economies so tapping their vast potential for renewables is the obvious solution both for them and the climate. The challenge, as ever, is funding. To solve this, African nations are striking up international partnerships in a bid to unleash the full power of their phenomenal natural assets. … [Read more...]
How much subsidy does solar need, and for how long?
Schalk Cloete presents his latest paper looking at what affects the profitability of an investment in a power sector. After reviewing onshore wind and nuclear, he now looks at solar. His analysis of coal and gas are to come. Intermittency, market share, maintenance, integration costs and other factors are modelled in detail to help predict solar’s future. *This article is brought to you via our new author platform. If you have an article you … [Read more...]
“Consuming less energy may act as disincentive for investment in renewables”
According to Anthony Patt, Professor of Climate Policy at the ETH ZĂĽrich in Switzerland, the less we spend on energy, the less attractive renewables can look to businesses and investment markets. Such remarkable insights fly in the face of received wisdom and defy logic. Patt claims his models show that doubling current energy efficiency improvement rates buys us only one extra year to hit the Paris targets. Really? - This is how Anthony … [Read more...]
Electric metering should break its link with power consumed and create it directly with the costs of delivery
In a world where electricity is generated from non-renewables (oil, gas, nuclear) our meters measure and charge us for electricity delivered, as if it was a fuel being consumed. Going forward, the cost should be measured against what is actually being consumed. In a renewables world – particularly 'run-of-the-river' hydro, wind and solar - that’s not the electricity. It’s the wear and tear on the infrastructure. Treating these types of renewable … [Read more...]
Nuclear power at the mercy of government subsidies while costs remain high
What affects the profitability of an investment in nuclear energy? What are the risks? Energy researcher and analyst Schalk Cloete presents his latest paper on the matter. He looks at the various effects on nuclear power investment, including the rise of other competing renewable energy sources, and the changing price of energy. *This article is brought to you via our new author platform. If you have an article you want to submit to us for … [Read more...]
Energy Efficiency targets: Time to ramp up investment in buildings, industry and vehicles
Energy efficiency investment rates need to double now, and then double again in 2025, to meet energy efficiency’s obligation to hitting the Paris targets. Right now there is a €130bn annual energy efficiency investment gap in Europe. Peter Sweatman, Rapporteur for EEFIG, looks at the assets themselves and says we need to productise the measurement of their energy efficiency, and then legislate. That’s how to make energy efficient homes, offices, … [Read more...]
