Solar vs Power Stations
How efficient are solar panels compared to power stations?
Solar panels vs power stations efficiency comparison: COAL: 33% efficient. Fuel cost: high. CO₂: 900g/kWh. Status: UK phasing out by 2024 (done). GAS (CCGT): 55% efficient. Fuel cost: volatile. CO₂: 400g/kWh. Status: still 35% of UK grid. NUCLEAR: 33% efficient. Fuel cost: low. CO₂: 12g/kWh. Status: reliable baseload. WIND: 35-45% capacity factor. Fuel cost: FREE. CO₂: 11g/kWh. Status: UK's largest generator. SOLAR: 20-22% efficient. Fuel cost: FREE. CO₂: 20-50g/kWh (lifecycle). Status: fastest growing. KEY INSIGHT: Efficiency percentage is misleading. Solar's fuel is FREE and unlimited. A 33% efficient coal plant burns expensive fuel and pollutes. A 20% efficient solar panel converts free sunlight into free electricity forever.
