50% off electronics' greenhouse gases, the world's largest tidal plant, and a hydrogen fuel cell that powers 3000 homes are just some of the impressive Korean green business initiatives.
The first, Samsung has just announced over 4 billion dollars of investment to green its electronics. It will cut the greenhouse gas embodied in its products by 50%. Once past the factory gate goods also use power and, Samsung says, its TVs, refrigerators and air conditioners will be the most efficient (lowest power use) products available.
Efficiency is also central to the stationary hydrogen fuel cell. The plant producing heat & electricity for 3000 homes does so by using 80% of the available energy from gas for a current cost of about AUD 0.23 per unit.
And the world's largest tidal power plant - it will deliver power at approximately half the cost of wind power. Hydrogen and tidal power plant pictures and detail are here. Cost comparisons here.
