Japan is always at the cutting edge of technology, and is one of the world’s leading solar panel manufacturers. It has been steadily increasing its own solar power infrastructure since the 1990s, and now ranks in the top 5 countries in terms of the number of solar photovoltaic panels installed.
In 2008, the Japanese Ministry of Economy, Trade & Industry set a target of 70% of newly-built homes being able to generate their own solar power. In 2009, they said they were aiming for 10% of all primary domestic energy demand to be met through solar PV by 2050.
At the time, these seemed like reasonably ambitious goals. Since then, however, Japan has experienced a devastating earthquake and tsunami, which led to a major (and ongoing) crisis at the Fukushima Daiichi nuclear power plant. This has prompted Japan to re-evaluate its dependence on nuclear, and reappraise the energy-generating potential of solar.
Japan is now considering legislation that would require all new buildings, both residential and commercial, to be fitted with rooftop solar panels by 2030. It is expected that Prime Minister Naoto Kan will announce this at the 37th G8 Summit, taking place from 26-27 May in Deauville, France.
In order to cut greenhouse gas emissions, Japan had planned to increase nuclear energy production so that it would provide over 50% of the country’s electricity by 2030, but this now looks highly improbable.
Meanwhile, Japanese telecom company Softbank has announced that it plans to invest $97 million in an ‘Eastern Japan Solar Belt’. CEO and president Masayoshi Son is the richest man in Japan, and has been vocal in the campaign for a departure from nuclear. He will be launching a ‘Natural Energy Council’ with local authorities in July in order to promote renewable power.
Japan is by no means alone in its enthusiasm for solar power – a new report from consultancy firm KPMG suggests that falling costs mean that solar can provide 7% of India’s total power by 2022, reducing the country’s CO2 emissions by 2.6% and creating major employment opportunities.
The UN’s Intergovernmental Panel on Climate Change (IPCC) has also produced a report, suggesting that as much as a third of the planet’s entire electricity supply could be delivered through solar PV by 2050. The IPCC has projected that up to 77% of global energy demand could be met using renewable sources (including solar) by 2050, but stressed that this would require $12 trillion of investment over the next 2 decades, and acknowledged that their would be serious technical and political obstacles.
The events in Japan have had a tragic human cost, causing suffering on an incomprehensible scale. One positive outcome of the disaster, however, could be a safer, greener and more secure future for the country. Indeed, this could yet be a turning point for global attitudes towards energy and environmental issues, but nothing should be taken for granted.
