energy alternatives

As nations scramble to shore up energy resources and avoid geopolitical conflict over increasingly scarce fossil fuels, scientists and entrepreneurs in many innovative nations are pioneering energy-efficient solutions.

Yet, alternative sources of energy such as wind, tidal and solar are often expensive and inefficient.

Around the globe, individuals, companies and governments are developing new ways to power their businesses, heat their homes and run their cars. Worldfocus examines how countries such as China, Denmark, Brazil and Israel are investing in alternative energy and developing technologies that lessen our dependence on fossil fuels.

China surges past competitors in clean energy technology

China is rapidly becoming the leading manufacturer of clean energy. The country has become the largest producer of wind turbines and solar panels and also provides almost 97 percent of the world's supply of rare-earth materials. The world's biggest greenhouse gas emitter could also make the rest of the world reliant on its alternative energy products.

China’s air quality improves but remains highly polluted

In our broadcast this week, we showed how some Chinese drivers are opting for knockoff electric cars that are non-polluting and cheap -- but the electricity that these vehicles use is generated by coal, which increases air pollution and greenhouse gases. We take a deeper look at China's battle against air pollution, courtesy of the Asia Society's China Green multimedia project.

‘Bootleg’ electric cars thrive in China’s second-tier cities

In China, we meet a modern-day Thomas Edison who helped give birth to the country's "knockoff" electric car industry. Chinese consumers in second-tier cities can't get enough of these small, cheap electric cars that require 6 hours of charging to go 75 miles -- at a maximum of 35 mph. Video journalist Jimmy Wang produced the video for TIME and the Asia Society.
