Hawaii uses mainly oil for its energy requirement such eletricity.
Unfortunately, oil has several disadvantages: it is an exhaustible energy source, very expensive and it contributes to global warming on long term.
Nevertheless ,planners decide to exploit renewable sources of country like wind or sun. Hawaii is composed of 6 islands. Among these islands, Oahu is many more populated than the other.So consumption of eletricity is very important.However, renewable sources is an alternative at this problem,but the most interesting renewable energy are far from Oahu and it can not directly exploit. That is why, cable which links all islands together and which carries energy one island to another seem to be a good solution.Besides,energy arrives on the grid electric set up in each island.Grid electric converts renewable energy into eletricity.
According to Lind Lingle, Hawaii has two objectives to reach. on the one hand, it's to carry energy produced by wind farm (or sun, wave)on the islands sparsely populated until Oahu by means undersea cables, on the other hand to produce 40% of energy from renewable energy to the people who need it.
To reach the obejctives, planners suggest to connect six grids of each island by cable and hope to reduce eletricty consumption from air conditioning. Consequently,Honolulu will be able to receive almost all the energy from other islands through cables.
Finally, state helps financially developers to build their own renewable
