Energy rates in China are not set by one national price. Electricity prices vary by province, customer type, and time of use. Residential users may pay tiered rates, while factories often face hourly market prices. Peak periods cost more. Off-peak power can be noticeably cheaper. A fair comparison should use the same location and annual consumption. Otherwise, the result becomes misleading.
Natural gas rates depend on city distribution rules, import costs, storage, and winter demand. They may rise when temperatures fall and supply tightens. Coal is different. Consumers rarely buy it through a simple household tariff. Its economic rate includes fuel costs, transport, plant efficiency, and pollution controls. Coal-fired power can look inexpensive at the generator. However, grid and environmental costs are easy to overlook. That is the uncomfortable part.
Renewable energy rates, especially solar and onshore wind, have fallen through larger projects and better equipment. Still, a low generation price does not mean a low delivered price. Transmission, balancing, storage, and backup capacity add costs. In practice, I would compare the final bill, not only the advertised kilowatt-hour rate. Check provincial tariff notices and recent monthly usage. Small household samples can distort the picture. My comparison would also separate price from reliability, because cheap power is less useful during an evening demand peak.
