New energy construction needs to be cautious

In recent years, new energy sources are not hot. When you open a newspaper, you often build a new energy base in a certain province or focus on investing in new energy projects. At the same time, the professional and scientific achievements related to new energy sources are also extremely difficult. It can be said that in the face of the depletion of traditional domestic energy sources, everyone has put expectations on new energy sources. According to Xiao Bian, new energy investment needs to be cautious.

First of all, Xiaobian, first of all, is familiar with what new energy is. New energy is also called unconventional energy. It refers to various energy forms other than traditional energy sources. Refers to energy that has just begun to develop or is being actively researched and yet to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy.

According to Xiao Bian, the reason why new energy is popular is due to the following reasons: 1) It is rich in resources, generally has renewable characteristics and can be used by humans forever; 2) it is carbon-free or contains very little carbon. , The impact on the environment is small; 3) The distribution is wide, which is conducive to the small-scale decentralized use.

However, when people blindly develop new energy sources, they often only notice its merits and neglect its major drawbacks. First, many new energy sources have low energy density, and development and utilization require more space, such as wind power and solar energy. Second, New energy is often an intermittent supply, with high volatility and unfavorable for continued energy supply. Finally, with the exception of hydropower, renewable energy is more expensive to develop and use than fossil fuels. The most important point is that many new energy sources have great safety risks. Nuclear power is one of the representatives.

In recent years, with the continuous expansion of new energy projects, these drawbacks have gradually surfaced. The first is the unplanned expansion of wind energy, which results in overcapacity of wind energy and a large loss in the wind energy industry. Second, the excessive photovoltaic costs lead to the ups and downs of the photovoltaic industry; the most serious is nuclear energy. The safety and economics of the leakage accident at the Fukushima nuclear power plant in Japan for the whole of Southeast Asia. All have a certain impact. Therefore, as far as Xiaobian is concerned, new energy is indeed a double-edged sword. When everyone is paying attention to its good side, it must also be vigilant against the hidden dangers it may bring. It is also necessary to be cautious when investing in new energy sources.
