Since the 2011 disaster, Japan’s nuclear
power program, which had provided about 30% of the country’s electricity, has
ground to a halt amid public anxiety over safety, and the country has had to
fill much of the gap by burning fossil fuels, taking a look back into late 90s
energy production strategies.
The government has been trying for
months to get the public consensus before turning some reactors back on, but so
far its assurances that new, tighter regulations will keep the plants safe have
not convinced many Japanese, on the contrary to what lobby’s argue as a symptom
of losing competitivty in the international market, where there has been an
increasing necessity to buy materials for burning fossil fuels. In 2013,
Japan released the equivalent of 1.2 billion metric tons of carbon dioxide,
more than 7% higher than the year preceding the nuclear accident and 14% higher
than levels in 1990.
In 2011, Japan was the world’s
fifth-biggest emitter of carbon dioxide, after China, the United States, India
and Russia. Together, these countries and the European Union account for about
70% of total global carbon dioxide emissions, according to the Environmental
Protection Agency in the United States. Japan had been reluctant in pursuing
renewable energy, choosing instead to rely on its reactors to avoid greenhouse
emissions. As a result, before the accident, less than 3% of the electricity
Japan generated came from renewable energy sources.
To commence its renewable power program,
Japan introduced incentives to diversify its energy sources last year. In the
program’s first 12 months, through June, the country added renewable power
equal to the output of about four nuclear reactors.
Japan’s new target assumes that the
country will achieve energy savings of about 20% by investing in renewable
energy sources and energy-efficient technology. Japan seeks to reduce emissions
from 2005 levels by 3.8%. Japan’s nuclear reactors around the country were shut
down for regular maintenance after the disaster at Fukushima Daiichi spewed
radioactive materials over northeastern Japan, but the government did not count
on the antinuclear feelings that greeted its attempts to try to restart them.
Now, the necessity to implement renewable energy systems urges while Kyoto
Protocol top emissions limit are not meet and the dependence on foreign
materials to produce energy alerts its government.
Japan’s environment minister, Nobuteru
Ishihara, said that the new target “does not consider the possible effect of
nuclear power plants reducing emissions” and that Japan “would set a more
definite target” once it settled on what sources of energy it would use in the
future.
For this reason, Martin Kaiser, head of
the Greenpeace delegation affirmed that “Japan can get dramatic emission
reductions while shutting down nuclear entirely,” Greenpeace said its own
calculations showed Japan could achieve emissions cuts of more than 20"
without relying on nuclear power if it more aggressively pursued renewable
energy.
In conclusion, those countries which were
already transitioning into renewable energy sources do not solely depend on
autonomous independent sources of energy production, but rather can diversify
its energy production promoting its results. As a consequence, their dependence
to foreign markets tends to zero while their know-how continues to advance where the
versatility of merging renewable sources with other's production themes could
be of intangible benefit for the society, in terms of economic advance as well
as prosperity for the nation, defining a future strategy opting for the best
model of energy production once different techniques have been evidenced.
