China’s Three Gorges Dam: This Dam affected Earth’s Rotation

~ Đào Thu Hằng ~ Bình luận về bài viết này

The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River, in Central China. It is the world’s largest hydroelectric power station, but all that power comes with great responsibility. According to NASA, the dam delays the rotation of the Earth by 0.06 microseconds. This happens when the dam raises trillions of pounds of water 574 feet (175 m) above sea level increasing the Earth’s moment of inertia and thus slowing its rotation. Will the dam cause major consequences in our future or will the very minor delay not be noticeable for thousands of years?

China’s plan for the ‘world’s riskiest’ mega dam high in the Himalayas

~ Đào Thu Hằng ~ Bình luận về bài viết này

As China seeks to meet its targets of becoming carbon neutral by 2060, it is turning its sights to some of the wildest reaches of the Tibetan Plateau where it plans to build a hydropower plant so ambitious that it could produce three times as much power as Three Gorges.

Experts believe it could be the riskiest mega structure ever built. Not only is the location prone to massive landslides and some of the most powerful earthquakes ever recorded, it’s also precariously close to the disputed border between India and China. Meaning any major project could further escalate discontent in a tense territorial dispute between the world’s two most populous countries.

The Role of Concessional Climate Finance in Accelerating the Deployment of Offshore Wind in Emerging Markets

~ Đào Thu Hằng ~ Bình luận về bài viết này

Offshore wind will be critical to achieve the world’s decarbonization and sustainable development goals. Although the cost of offshore wind has dropped dramatically over the past decade, there will be an initial cost premium when developing offshore wind in emerging markets due to a variety of risks and constraints in establishing a new market. Concessional climate finance could help countries overcome this initial cost barrier to help reduce costs for future projects and lay the foundation for the development of successful offshore wind markets.  

This report from World Bank’s Energy Sector Management Assistance Program (ESMAP) and International Finance Corporation (IFC), finds that concessional climate financing is essential to unlock offshore wind in emerging markets and estimates that US$15 billion in concessional climate financing, consisting of both grants and loans, could catalyze offshore wind deployment across ten emerging market countries.

It started with a bang at 3 a.m. Monday as the residents of Derna were sleeping. One dam burst, then a second, sending a huge wave of water gushing down through the mountains towards the coastal Libyan city, killing thousands as entire neighborhoods were swept into the sea.

More than 5,000 people are believed to have been killed with thousands more missing, though estimates from different Libyan officials and aid groups have varied and the toll is expected to rise.

The eastern Libyan city of Derna, the epicenter of the disaster, had a population of around 100,000 before the tragedy. Authorities say that at least 10,000 remain missing. CNN could not independently verify the figures.

Buildings, homes and infrastructure were “wiped out” when a 7-meter (23-foot) wave hit the city, according to the International Committee of the Red Cross (ICRC), which said Thursday that dead bodies were now washing back up on shore.

But with thousands killed and many more still missing, there are questions as to why the storm that also hit Greece and other countries caused so much more devastation in Libya.

Experts say that apart from the strong storm itself, Libya’s catastrophe was greatly exacerbated by a lethal confluence of factors including aging, crumbling infrastructure, inadequate warnings and the impacts of the accelerating climate crisis.

Key Findings

The Philippines spent nearly US$90 million on its first two shipments of liquefied natural gas (LNG). The price tag for just two cargoes should be a warning sign for the exorbitant LNG import bills to come. 

   

The Department of Energy’s draft circular aiming to make the country “a major player” in Asia “through the development and operation of LNG facilities” could increase the country’s dependence on one of the most expensive fuels available.

London’s High Court has ruled that two investors in Spanish solar energy plants are entitled to seize a Spanish property in London to enforce a judgment in a long-running dispute over renewable energy incentives.

The court’s interim charging order – meaning it is not yet final and can be objected to by the debtor – was issued on Wednesday but made public on Friday.

Renewables Competitiveness Accelerates, Despite Cost Inflation

Abu Dhabi, United Arab Emirates, 29 August 2023 – The fossil fuel price crisis has accelerated the competitiveness of renewable power. Around 86 per cent (187 gigawatts) of all the newly commissioned renewable capacity in 2022 had lower costs than fossil fuel-fired electricity.

Renewable Power Generation Costs in 2022, published by the International Renewable Energy Agency (IRENA) today shows that the renewable power added in 2022 reduced the fuel bill of the electricity sector worldwide. New capacity added since 2000 reduced the electricity sector fuel bill in 2022 by at least USD 520 billion. In non-OECD countries, just the saving over the lifetime of new capacity additions in 2022 will reduce costs by up to USD 580 billion.

Fossil Fuel Subsidies: WHY DO WE CARE ABOUT FOSSIL FUEL SUBSIDIES?

Why do we care about fossil fuel subsidies?

Subsidies are intended to protect consumers by keeping prices low, but they come at a substantial cost. Subsidies have sizable fiscal consequences (leading to higher taxes/borrowing or lower spending), promote inefficient allocation of an economy’s resources (hindering growth), encourage pollution (contributing to climate change and premature deaths from local air pollution), and are not well targeted at the poor (mostly benefiting higher income households). Removing subsidies and using the revenue gain for better targeted social spending, reductions in inefficient taxes, and productive investments can promote sustainable and equitable outcomes. Fossil fuel subsidy removal would also reduce energy security concerns related to volatile fossil fuel supplies.

WASHINGTON, June 15, 2023 – Trillions of dollars are wasted on subsidies for agriculture, fishing and fossil fuels that could be used to help address climate change instead of harming people and the planet, a World Bank report says.

The report, Detox Development: Repurposing Environmentally Harmful Subsidies, says global direct government expenditures in the three sectors are $1.25 trillion a year—around the size of a big economy such as Mexico. To subsidize fossil fuel consumption, countries spend about six times what they pledged to mobilize annually under the Paris Agreement for renewable energies and low-carbon development.

Financing the Coal Transition

~ Đào Thu Hằng ~ Bình luận về bài viết này

This report aims to contribute to growing conversations about coal finance mechanisms, particularly as they move from concept to reality. RMI believes that financial mechanisms can be a transformational tool in coal transition efforts—but only if implemented well. Ultimately, the devil will be in the detail as to how financial mechanisms are designed and governed to meet the critical needs of all stakeholders and help deliver a rapid and smooth pathway to a climate-safe future.

RMI’s report, Financing the Coal Transition, shows how financial mechanisms can complement policy and regulation to help achieve a rapid, equitable, and smooth coal transition.

The economics of power generation are shifting rapidly in favor of clean energy, challenging coal’s long history as a mainstay of economic development throughout the world. However, much more work needs to be done to transition the existing coal fleet in line with climate and development goals.

The privileged place coal has occupied in power generation for over a century has entrenched complex barriers—from the way that grids have been built to the incentive structures within electricity systems—that prevent markets from catching up to the economic trend toward clean energy. In the absence of solutions to address these barriers, the costs of uneconomic coal will fall largely on local communities through direct costs and unpriced impacts on local health and the environment.

The global community needs new solutions to address the social and economic complexities of the coal transition while responding to the urgency of the climate challenge. One set of solutions currently under development are the innovative financial mechanisms designed to support the transition from coal to clean energy.

This report helps make sense of the various financial mechanisms proposed to date, and models the impacts of using different financial mechanisms to transition existing coal power plants. While it finds that financial mechanisms have the potential to generate wins for both the climate and communities, it also recognizes the risks of using finance to support the coal transition. To manage these risks, RMI proposes five key principles to guide the design of credible financial mechanisms.

PARIS, Dec 9 (Reuters) – France is bracing for possible power outages in the coming days as falling temperatures push up demand while state-controlled nuclear group EDF struggles to bring more production on line.

WHY CAN’T FRANCE MEET DEMAND?

France is one of the most nuclear-powered countries in the world, typically producing over 70% of its electricity with its fleet of 56 reactors and providing about 15% of Europe’s total power through exports.
