煤炭是我国的主体能源，在相当长时期内仍将是我国能源安全的基石。

Money is overrated. Truly new things rarely need an abundance of money. If that was so， billionaires would have a monopoly on inventing new things， and they don’t. Instead almost all breakthroughs are made by those who lack money， because they are forced to rely on their passion， persistence and ingenuity to figure out new ways. Being poor is an advantage in innovation.
