Climate Crisis: We're Solving It?!

What It Covers

Climate scientists Sven Teske and Wei Hsu explain how solar and wind power now cost less than fossil fuels, why individual actions matter less than policy change, and which technologies can realistically achieve net zero emissions by 2050.

Key Questions Answered

• •Renewable energy economics: Solar and wind now cost 3-4 cents per kilowatt hour compared to 10 dollars thirty years ago, making them cheaper than any fossil fuel. China builds 1,200 megawatts of solar capacity daily, driving costs down through massive economies of scale.
• •Electric vehicle efficiency: Petrol cars waste 80% of fuel energy through heat loss, achieving only 20% efficiency at the wheels. Electric motors operate at 90-95% efficiency, making EVs cleaner even when charged from fossil fuel grids. China's EV growth caused the first-ever decline in oil demand.
• •Carbon offset limitations: Tree planting offsets take 10-15 years to sequester carbon and release it all back when forests burn. Offsets allow companies to continue emissions rather than reduce them, creating measurement and verification problems that enable greenwashing by fossil fuel companies claiming net zero targets.
• •Nuclear power costs: Nuclear plants take 12 years average to build versus months for solar farms, cost 6-10 times more per kilowatt than renewables, and require billions for decommissioning plus perpetual waste storage. Germany spent 50 billion dollars building nuclear fleet and another 50 billion decommissioning it.
