The Bjarke Ingels Group or BIG made the cleanest waste-to-energy power plant in the world. The power plant, which is located in Copenhagen, Denmark, has an artificial ski slope that is open all year around. The power plant is also home to a rooftop bar, a cross-fit area, 85 meter high climbing wall and a 490 meter long hiking path. The power plant is part of a plan to make Copenhagen the first carbon-neutral city in the world by 2025. The power plant can turn 440,000 tons of waste into energy that will power 150,000 houses and power itself. The power plant is not only better for the environment, but also betters the lives of the people in Copenhagen. Bjarke Ingels, the founder of BIG, says, “CopenHill is a perfect example of the world changing power of architecture. That we have the power to give form to the future we want to live in” (Crook).

The Bullitt Center located in Seattle, Washington is known as one of the most environmentally friendly buildings in the U.S. and maybe even the world. The office building is home to 14,303 solar panels. The building also has automated windows that open at night to cool the building. An average Seattle office building uses about 30 to 40% of energy to heat and cool the building but the Bullitt Center only uses 2 to 3% for heating and cooling. The building generated 60% more electricity than it used in the first year it was in operation. Jason McLennan, a chief executive of the institute says, “It is a pretty big achievement. It shows how close we are to a fossil-fuel-free world.” The Bullitt Center is proof of how it can be done (La Ganga).
