From the first-time mankind drilled wood for fire to the use of fossil energy, it was the continuous progress and innovation of energy that propelled human society to leapfrog from the age of fuelwood to the age of electricity. Nowadays, the humankind's demand for building a green, low-carbon and sustainable society is growing day by day. This has in turn led to a huge change in the structure of energy, from fossil energy to the promotion and popularization of renewable energy sources, such as wind and nuclear energy. The continuous development of green, low-carbon, clean and sustainable energy will surely illuminate the direction of human society and push the train of the times to set sail again.
