EVs beat petrol cars on lifetime emissions — even on “dirty” grids. Battery production is carbon-intensive, but EVs quickly repay that debt and end up 21–71% cleaner over 250,000 km. We can’t wait for perfect grids: electrify transport and clean the grid now.

Over 20,000 sheep under solar panels create a desert miracle! In northwest China's Qinghai Province, the land was once desert. The panels block wind and sunlight, allowing grass to grow and turning desert into grassland.

More solar was installed globally in first 4 months of 2025 than in all of 2022! New battery storage is also setting global records in 2025. Wind too likely sets a new global record for deployment in 2025. EVs have record sales in 2025. Petrostate politicos freak out.

Generating electricity from fossil fuels is very inefficient. Moving from coal to solar reduces primary energy consumption by 2/3 at the point of electricity generation.

NEW RECORD: British solar generation just surpassed its 2024 total. This milestone shows potential of renewables, but also highlights need for smarter grid. To maximise benefits of solar we must tackle grid bottlenecks, streamline planning & prioritise system-friendly operation.
