石油和瓦斯(所有化石燃料) 雖然名義上看來便宜，但是真實成本是很少被面

Oil and gas (all fossil fuels) are nominally cheap, but the real cost is rarely faced. These non-renewable energy sources are produced in the earth for millions of years, and usually use "free" to calculate the production cost; only the mining cost is calculated. Although it is possible to provide part of the hydrogen demand as a by-product of the petrochemical industry, any wattage of hydrogen energy beyond this part is still more expensive than other renewable energy sources (such as solar energy)

Oil and gas (all fossil fuels) may seem cheap in nominal terms, but the true costs are rarely faced. These non-renewable sources of energy are millions of years old and are generated inside the Earth, often using "free" to calculate production costs; Although a portion of hydrogen demand can be provided by petrochemical industry by-products, any wattage beyond this is more expensive than other renewable energy sources (e.g. solar).

Oil and gas (all fossil fuels) are nominally cheap, but the real costs are rarely faced. These non renewable sources of energy take millions of years to generate in the earth's interior, usually using "free" to calculate the cost of production; only the cost of mining. Although a part of the hydrogen demand can be provided by-products of the petrochemical industry, any number of watts of hydrogen beyond this part is still more expensive than other renewable energy sources (such as solar energy)<br>
