China’s Three Gorges Dam generates record amount of power
The electricity generated by the Three Gorges Dam, the structure straddling the Yangtze River in China's Hubei province, has exceeded 100 billion kilowatt hours, setting a record for a single hydropower station in China, and also outperformed the dam's 2018 target of 92.3 billion kilowatt hours.
By the end of this year, the accumulated power will total close to 1.2 trillion kilowatt hours.
In 2018, the upper reaches of the Yangtze River received a large amount of rainfall. CTG (China Three Gorges Corporation), the builder and operator of the dam, manages to recycle small and medium-sized floods by promoting forecast capacity on water and rain conditions, analysing the coming water volume, and enhancing scheduling ability and joint operations of cascade hydropower stations.
This year, the generator ran for 1,184.37 hours, including 352.38 hours at full capacity, and the accumulated power added 5.2 billion kilowatt hours under conditions that conserved water.
The 100 billion kilowatt hours of electricity generated by the dam is equivalent to a reduction of 31.9 million tons of coal and 85.8 million tons of carbon dioxide. The 100 billion kilowatt hours of electricity can support the creation of a GDP in China worth 1.2 trillion yuan ($170 billion), provided every kWh of electricity could create a GDP of 12 yuan.
The Three Gorges Dam is the world's largest hydropower project, and a power supplier in China that bears the task of facilitating west to east electricity transmission and south and north power complementation. It has a combined generating capacity of 22.5 GW and a designed annual generation capacity of 88.2 billion kilowatt hours.
The dam has contributed to the maintenance and promotion of the Yangtze River Economic Belt, driven clean energy production, and served the country's energy structure adjustment.
All but two UK regions failing on school energy efficiency
Most schools are still "treading water" on implementing energy efficient technology, according to new analysis of Government data from eLight.
Yorkshire & the Humber and the North East are the only regions where schools have collectively reduced how much they spend on energy per pupil, cutting expenditure by 4.4% and 0.9% respectively. Every other region of England increased its average energy expenditure per pupil, with schools in Inner London doing so by as much as 23.5%.
According to The Carbon Trust, energy bills in UK schools amount to £543 million per year, with 50% of a school’s total electricity cost being lighting. If every school in the UK implemented any type of energy efficient technology, over £100 million could be saved each year.
Harvey Sinclair, CEO of eEnergy, eLight’s parent company, said the figures demonstrate an uncomfortable truth for the education sector – namely that most schools are still treading water on the implementation of energy efficient technology. Energy efficiency could make a huge difference to meeting net zero ambitions, but most schools are still lagging behind.
“The solutions exist, but they are not being deployed fast enough," he said. "For example, we’ve made great progress in upgrading schools to energy-efficient LED lighting, but with 80% of schools yet to make the switch, there’s an enormous opportunity to make a collective reduction in carbon footprint and save a lot of money on energy bills. Our model means the entire project is financed, doesn’t require any upfront expenditure, and repayments are more than covered by the energy savings made."
He said while it has worked with over 300 schools, most are still far too slow to commit. "We are urging them to act with greater urgency because climate change won’t wait, and the need for action gets more pressing every year. The education sector has an important part to play in that and pupils around the country expect their schools to do so – there is still a huge job to be done."
North Yorkshire County Council is benefiting from the Public Sector Decarbonisation Scheme, which has so far awarded nearly £1bn for energy efficiency and heat decarbonisation projects around the country, and Craven schools has reportedly made a successful £2m bid (click here).
