Introduction
From the second we wake up and even while we are asleep we are using energy resources. Generating the electricity we use makes a significant contribution to climate change. In this topic we will study our options for power generation and the problems associated with them.

Task 4c: Answer these questions
Answers
Gas without carbon capture storage. [1]
i. Capital costs for wind and solar power much higher for same power output. [1]ii. Nuclear and coal-fired power capital costs much higher for same power output, [1] when include carbon capture storage higher overall costs for gas-fired/oil power. [1]
4000MW × 30 years = 4 × 106 kW × (30 × 365 × 24) = 1.05×1012 kWh [1] Decommissioning cost per kWh = £1000 million/1.05×1012 ≈ 0.1p/ kWh [1]
