Renewable Energy Explained

Falling costs make renewables the cheapest new power in most regions.

Renewable Energy Explained

Solar and Wind

Photovoltaic costs dropped 90% in a decade. Wind capacity factors improve with taller turbines and offshore farms.

Intermittency Solutions

Grid-scale batteries, pumped hydro, demand shifting, and geographic diversity balance variable supply.

Nuclear Role

Existing nuclear provides steady baseline power. New modular designs may complement renewables long term.

Transition Reality

Full decarbonization requires electrifying transport and heating, not just building more solar panels.
