TOKYO: Japan needs to boost renewable energy by reforming outdated policies on land use and the national grid if it is to meet a new goal of carbon neutrality by 2050, industry players and experts say.
Since announcing the 2050 target in November, Prime Minister Yoshihide Suga's government has pledged to spend $20 billion on green tech and set ambitious new wind power targets.
But the world's third-largest economy has a lot of catching up to do, said Ken Isono, CEO of renewable energy company Shizen Energy.
"Japan could be a leading country in solar, 15 years ago it used to be," he told AFP.
"But I think Japan lacked vision and so it got totally left behind."
Critics have long bemoaned a lack of ambition in Japan's policy, which currently aims for 22-24 percent of the country's energy to come from renewables by 2030.
Around 17 percent already came from renewables in 2017, and a combination of growth in the sector and a pandemic-related fall in demand means Japan is on track to meet its 2030 target this year.
Japan was the sixth-biggest contributor to global greenhouse emissions in 2017, according to the International Energy Agency. It relies heavily on coal and liquefied natural gas, particularly with many of its nuclear reactors still offline after the 2011 Fukushima accident.
Isono, whose firm works in solar, wind and hydroelectric, thinks the government should set a goal of "at least 40 percent" renewable energy by 2030, which he calls realistic rather than visionary.
But getting there will require concrete action, particularly on land use, he argued. Japan is sometimes assumed to struggle with renewables because its mountainous territory is ill-suited for solar and wind installation. But Isono said that is "an excuse", pointing to the country's comparatively abundant abandoned and underutilised farmland.
"The average age of most farmers in Japan is almost 70 years old. In five or 10 years, nobody is going to be doing agriculture... How can we create energy from that land?" he said. Isono favours legal reforms to make it easier for municipalities to take over such land and use it for renewable energy projects, an idea backed by others in the sector and some in government. Freeing up farmland would mostly benefit solar, which dominates Japan's renewable sector because panels are comparatively easy to install and maintain, and offer flexibility in terms of project size.
But there are also some specific factors holding back other options, including wind power, according to Mika Ohbayashi, director of the Renewable Energy Institute, a think tank in Tokyo.
