Nuclear energy not the only option

By Gloria Hsu 徐光蓉

At a summit on Tuesday last week on the prospects for developing renewable energy sources, President Ma Ying-jeou (馬英九) said that there was no way renewable energy sources would be able to replace nuclear energy in the foreseeable future.

With these remarks Ma not only hurt renewable energy operators, but also promoted nuclear power.

Since Japan’s Fukushima Dai-ichi nuclear power plant disaster in 2011, opinion polls conducted in Taiwan have shown that more than half of respondents, regardless of their political background, are against nuclear power.

However, the government still seizes every opportunity to push its biased ideas about nuclear power.

At the end of last year, the total installed capacity of global nuclear power was 390 GW, while that of renewable energy was 1,470 GW.

Even if we exclude hydroelectric power at 990 megawatts, solar power, wind power and biomass have a combined installed capacity of 480 megawatts, which is higher than that of nuclear power.

Since its introduction, global hydroelectric generation has always been higher than nuclear power generation, and in 2011, solar and wind power generation increased to a level equivalent to 40 percent of global nuclear power generation.

Moreover, the production of renewable energy sources is increasing at a faster pace than nuclear power production which has stagnated and is gradually decreasing.

An article entitled Nuclear power: The dream that failed that appeared in last year’s March 8 edition of The Economist, one year after the Fukushima Dai-ichi disaster, stated that nuclear power was uneconomical and facing ever-increasing competition from affordable renewable energy sources.

The government often deliberately distorts the question of whether it is possible to replace nuclear power with renewable energy so that it becomes a question of whether renewable energy can replace nuclear power all at once, as if instant rather than gradual replacement were the only alternative to nuclear power generation.

In 2001, Germany’s total power consumption was approximately three times that of Taiwan’s, with 30 percent coming from nuclear power and less than 7 percent coming from renewable energy.

A decade later, Taiwan’s power consumption has increased by 30 percent, while the same figure for Germany increased by only 5.6 percent.

The difference has decreased, and Germany’s power consumption is now only twice that of Taiwan’s. In addition, nuclear power makes up less than 20 percent of Germany’s power consumption while the proportion of renewable energy has increased to more than 20 percent, making it obvious that nuclear power is being replaced by renewable energy.

In 2020 — Ma’s “foreseeable future” — Germany’s use of nuclear power is projected to be almost zero, while 35 percent of its power is projected to come from renewable energy sources, which in addition to nuclear power will begin to replace conventional coal-fired electricity generation.

Denmark, a country of roughly the same size as Taiwan, has no nuclear power. Early on, Denmark relied almost exclusively on imports for its energy needs. After the 1973 oil crisis, the country focused on increasing energy efficiency and developing renewable energy sources.

By 2011, energy consumption had decreased by 1.4 percent from 1990, although its GDP had increased by 40 percent. Renewable energy sources now provide one-fourth of Denmark’s energy needs, with more than 40 percent coming from renewable sources, three-quarters of which is in the form of wind power. It is estimated that by 2035, renewable sources will supply all of Denmark’s energy demand, and that by 2050 renewable energy sources will replace all fossil fuels.
