Why should we vigorously develop new energy industry, especially the solar energy industry?
First to answer this question：How long can humans extract energy from the earth?
Global oil reserves are only available for 54 years. America is the world's largest consumer of crude oil.
Recently, Dr. Christopher Ruhr, the global chief economist of the oil giant BP, released the 2012 BP World Energy Statistical Yearbook (hereinafter referred to as the "Yearbook") in Beijing, using data to outline the 2011 Energy background: In 2011, oil prices increased sharply, and Brent crude oil prices rose by 40% annually; global oil reserves could be used for 54 years, and last year all global net energy growth came from emerging economies. Fossil fuels continue to dominate global energy consumption with a market share of 87%. Although renewable energy is growing rapidly, it still accounts for only 2% of global consumption.
Last year, global oil production also increased by 1.3%, or 1.1 million barrels per day, with Saudi Arabia, United Arab Emirates and Qatar producing new highs. Saudi Arabia's oil production last year reached 11.611 million barrels per day, still topping the list of countries with the highest global oil production.
Consumption of 88 million barrels of oil a day
According to the Yearbook, by the end of 2011, global oil reserves were about 1.653 trillion barrels, and global oil reserves could be used for 54 years. Last year, BP reported that world oil reserves at the end of 2010 were 1.526 trillion barrels. According to the current very very conservative consumption rate of 0.8 billion barrels per day in the world, the current world oil reserves can be used for 54 years worldwide.
Although the oil and gas reserves in the strata cannot be estimated very accurately, according to a rough estimate by oil experts, humans have claimed about 500-800 billion barrels of oil from the world between 1973 and 1997. 85% of the reserves. Since then, the newly discovered oil fields have almost doubled their reserves. French expert Jarnesini believes that "as far as the known oil reserves are concerned, this figure is about 1 trillion barrels, enough for human consumption for 36-40 years (calculated at the current rate of oil consumption)." In addition to the 1 trillion barrels, there is about 1 trillion barrels of oil to be discovered. That is to say, there are a total of 2 trillion barrels of oil available for exploitation in the underground, which can be used for human consumption for nearly 80 years.
The United Nations International Energy Agency pointed out that the current proven oil reserves will not be affected by 2020. ExxonMobil, the world's largest oil company, believes that even with the current proven reserves, even if it is re-exploited for 70 years, it will not reach the bottom line. As new oil fields are discovered and exploration and mining technologies are improved, the time it takes for humans to use oil may be extended.
Secondly, coal and natural gas: natural gas 65 years, coal 169 years. Detailed data:
According to BP's World Energy Statistical Yearbook 2008, world primary energy consumption increased by 2.4% in 2007 – although it was slightly lower than the 2.7% growth rate in 2006, it was still above average growth for the fifth consecutive year. Level. The Asia Pacific region accounts for two-thirds of global energy consumption growth and continues to grow at a rate of more than 5% above average. However, Japan’s energy consumption fell by 0.9%. Energy consumption in North America recovered and rebounded from the decline in 2006, growing by 1.6% – a cup of the average of the past 10 years. China's energy consumption growth rate last year was 7.7%, although it is still higher than the average of the past 10 years (the growth rate of China's economy in the same period is the same), it is the lowest growth rate since 2002. China once again occupies the general growth of global energy consumption. India's energy consumption has increased by 6.8%, the third largest growth in the world after China and the United States. The EU's energy consumption fell by 2.2%, with Germany's energy consumption falling the most in the world. Coal has become the fastest growing fuel for the fifth consecutive year.
Global coal consumption increased by 4.5%, higher than the 3.2% average of the past decade. Consumption growth is widespread, with the exception of the Middle East, where all regions have grown more than the average of the past decade. China’s coal consumption grew by 7.9%, the weakest blame since 2002, but still enough to account for less than two-thirds of global growth.
So this is the answer why should we vigorously develop new energy industry, especially the solar energy industry
