100 Percent Renewable Energy by 2030
A new two-part study published in the journal Energy Policy claims it's possible and affordable for the world to achieve 100 percent renewable energy by 2030.
Despite the "green" movement that has taken over the country in the last few years, more than 80 percent of the world's energy supply still comes from fossil fuels. Solar panels and wind turbines haven't been able to make much of a dent in coal and petroleum's dominance. But a new two-part study published in the journal Energy Policy claims it's possible and affordable for the world to achieve 100 percent renewable energy by 2030. The renewable sources of energy the researchers' calculations focused on included wind power, solar power, waves and geothermal energy, even as some question if solar power is worth the expense.
What do we see from watching birds move across the country?
- A total of eight billion birds migrate across the U.S. in the fall.
- The birds who migrate to the tropics fair better than the birds who winter in the U.S.
- Conservationists can arguably use these numbers to encourage the development of better habitats in the U.S., especially if temperatures begin to vary in the south.
Explore how alcohol affects your brain, from the first sip at the bar to life-long drinking habits.
- Alcohol is the world's most popular drug and has been a part of human culture for at least 9,000 years.
- Alcohol's effects on the brain range from temporarily limiting mental activity to sustained brain damage, depending on levels consumed and frequency of use.
- Understanding how alcohol affects your brain can help you determine what drinking habits are best for you.
If you want to know what makes a Canadian lynx a Canadian lynx a team of DNA sequencers has figured that out.
- A team at UMass Amherst recently sequenced the genome of the Canadian lynx.
- It's part of a project intending to sequence the genome of every vertebrate in the world.
- Conservationists interested in the Canadian lynx have a new tool to work with.
