The UN climate conference, attended by 192 countries and regions, will be held in Copenhagen, Denmark, in a month. This is not just a feast for environmentalists. The fierce debate and compromise made by global elites at the meeting to deal with climate change may bring earth shaking changes to the behavior, production and manufacturing of the whole human society.

The scientific community has issued a warning: to ensure that the global temperature rise is within 2 degrees Celsius, the carbon emissions of rich countries need to be reduced by 25% ~ 40% compared with 1990 by 2020, and the carbon emissions of poor countries cannot exceed the current peak in the next 15 years; Once the temperature rises above 2 degrees Celsius, global warming will be irreversible and catastrophic.

The energy industry will bear the brunt. At present, the carbon emission leading to global warming mainly comes from the extensive use of traditional fossil fuel dominated by oil, gas and coal. In the future, this will be unsustainable. Many countries and enterprises have already prepared for this. For example, the global investment in solar energy soared from US $600 million in 2004 to US $33.5 billion in 2008. In recent years, China has blossomed in nuclear energy, wind energy, solar energy and other fields.

The development speed of solar energy is on a par with that of wind energy. From 2004 to 2008, new investment in solar energy soared from US $600 million to US $33.5 billion. At the same time, the on grid power of solar energy increased by nearly 70% in 2008, which is the fastest among all renewable energy sources. Solar energy is mainly divided into heating and power generation, of which power generation accounts for the absolute majority.
