There may soon be more demand for renewable energy courses as the price of utilities goes up.
Gordon Miller, sustainability and communications director of Sustain Worldwide, said analysts believe energy costs will double by 2020 if they continue at their current rate of growth, which may make sustainable power more attractive.
If more people become interested in the possibilities offered by such techniques, there are sure to be more engineers keen to sign up for renewable energy courses.
Mr Miller said: "I believe that the vast majority of us will only act to be significantly more energy efficient when electricity and gas prices become prohibitively high."
He called on the government to make sure people engage with the upcoming Green Deal by ensuring that there are enough incentives, highlighting how important an effective marketing campaign will be.
This week, the Organisation for Economic Co-operation and Development encouraged governments across the world to look to the green sector for economic growth.
