Pumped Hydro as a Battery
Hydro power is about 10% of the global energy production, but pumped hydro is being pursued as part of the solution for intermittent storage in renewable energy

Underwater Power Cable for Renewable Energy
High Voltage DC transmission systems are driving underwater power cable for renewable energy transmitted over thousands of km from Africa to UK or Australia to Singapore. Cheap solar is driving the change.
Lithium amount in EV battery
What is the real figure of amount of lithium in a battery. The quantity of 6kg is elemental lithium. The quanty of Lithium carbonate equivalalent or LCE is used in mining circles and the quantity is about 60 kg. A large opportunity for efficiency improvement is clear.
Top 8 Lithium Miners by 2024
With established miners extracting lithium, who will be some of the up and coming miners. Here are 8 of them. There are another 150 miners globally.
10 Electric Vehicle Myths Debunked
Every new techology and disruption will have myths and falsehoods about how it will never happen. Here are 10 myths about electric cars – and many more to come.
10 Climate Change Denier Arguments
Climate change myths are everywhere, given that $200 million a year is spent on climate denial by fossil fuel companies. Recognise the arguments and understand the tactics of fossil fuel companies to protect their stranded assets.
Electric Airplanes Flying Soon
Airlines generally lose money. So electric, low carbon airplanes are being developed to reduce fuel costs – the largest cost after capital costs. What’s the latest development?
Home and Community Battery Storage
Home and community battery is a smart way to reduce transmission costs and to improve reliablity of renewable energy. Losses in transmission are about 10% and batteries cost much the same whether close to consumers or at a solar farm.
Recycling Effectiveness is Poor
Recycling effectiveness is poor because companies have passed the responsibility and cost of recycle / reuse onto consumers. Less than 7% of all plastic is recycled. Almost as much is dumped at sea. Time to change.
Enough Lithium Supply to meet Demand
When you dig into the supposed shortfall of lithium for EV and grid energy industry, it is clear that there is enough lithium to meet the demand although it will take time to come on stream.
