Wind Power is another option..
Brookfield Properties of Canada..just built the Strata condo tower in London
The first skyscraper to integrate wind turbines now in London, the Strata tower
London has yet another architectural marvel to brag about. The Strata will be the world’s first skyscraper to have built in wind turbines. Taking the concept of green sustainable architecture to a level above, the Strata tower, nicknamed “the Razor” uses a three wind turbines that will help meet 8% of its total energy needs. Standing 148 meters tall in the London horizon, this building was developed and contracted by Brookfield Europe. The 42 storey structure pops its head above all the other buildings in its vicinity, due to which it can effectively make use of the 35 mph wind speed. Special care was taken in its designing in order to make use of the Venturi effect created by nearby buildings that helps force wind through the turbines at higher speeds.
With a production rate of 50MWh of power annually, this building sure makes a eco-friendly statement in the architectural world.

Plans unveiled for world’s tallest tower in Saudi Arabia
The Saudi Royal family has unveiled plans to construct the world's tallest building, Kingdom Tower in Saudi Arabia, said to be one mile high.
The 275-floor Kingdom Tower in Saudi Arabia will be 1.6km tall and will be twice the height of the world's current tallest skyscraper, the Burj Khalifa in Dubai. The tower will include hotels, offices, luxury apartments and a shopping centre. It will also feature 12 million cubic square feet of interior space, which is about 12 times more than Canary Wharf in East London. It will be five times higher than the Shard of Glass in south London, which will be Britain’s tallest building post completion in 2012.
It will feature a balancing pendulum structure in its top to prevent it from toppling over. When the project was first announced in 2007, the architecture firm mentioned that the structure will feature wind-detecting sensors to direct stabilising aileron-like fins which will run along the length of the tower's frame to control resonant motion and drift.
The skyscraper will also be designed to be sustainable with a low environmental impact.
It will be equipped with wind turbines, photovoltaic panels, heliostats and sewage treatment facilities.
It is being financed by the Saudi Royal Family-owned Kingdom Holding Company, which is the country's largest company. The Kingdom Holding Company will construct an entire city around the skyscraper instead of constructing the tower in the centre of the city. An 8.9-square-mile city will be built in the costal area of Jeddah, which can accommodate 80,000 people and a further million visitors to the tower.
Kingdom Tower is expected to cost £12 billion ($19.6 billion) to construct and it will take 12 minutes to reach the top in a lift.
