Emissions of greenhouse gases and environmental pollutants are one of the biggest challenges of our time. We are contributing to solving the problem by developing new technology and making efficient use of natural resources. A few of these solutions are:
A few companies in the world are working to generate energy from the strong winds that blow out at sea. Floating wind turbines at sea work in the same way as a wind turbine on land. The turbines are kept afloat by technology equivalent to that used in offshore operations and can be installed at depths of between 120 and 700m. A wind turbine generates energy equivalent to the power consumption of 5000 households.
A wave power generator is a long installation that lies on the surface of the water and moves up and down and from side to side with water. Inside the generator, liquid is pumped under high pressure to hydraulic motors that drive electric generators. In this way the power of waves becomes electric current.
The tide contains enormous energy as it incessantly rolls in and out. This energy can drive under water turbines to generate electric current. Tides are more predictable than wind energy and solar power. Historically, tide mills have been used, both in Europe and on the Atlantic coast of the USA. The earliest occurrences date from the Middle Ages, or even from Roman times.
