The UK must recruit more than 100,000 people to fill green energy roles within a decade if the government hopes to meet its binding climate targets, National Grid has warned. A report by the company found that Britain needs to fill 120,000 roles in the green energy industry by 2030 to help develop projects that can cut greenhouse gas emissions to near zero. That number is likely to reach 400,000 by 2050, when the government expects to have developed a clean energy system based on renewable electricity, green heating systems and electric vehicles. The growing need for new recruits to power the UK’s climate targets is expected to emerge as Britain faces a green energy jobs crunch over the next 10 years. The report warned that a fifth of employees in the energy sector are due to retire by 2030.
