1 . About 12% of the total global energy demand comes from heating and cooling homes and businesses. A new study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this section by 40% in the US. The approach is called ATES, short for aquifer thermal energy storage (含水层热能储存).

“We need storage to absorb energy from the sun and wind. It’s crucial to creating affordable, reliable, and deeply environmental-friendly electricity systems. Most people are interested in batteries and other kinds of electrical storage. But we were wondering whether there was any opportunity to use geothermal (地热的) energy storage,” said first author A.T.D Perera. “With ATES, energy can be stored for a long period of time, without adding an additional burden to the grid (输电网).”

ATES is a pleasantly simple concept that takes advantage of the heat-absorbing property of water and the natural geological features of the planet. You simply pull existing underground water up and heat it at the surface in the summer with environmental heat or energy. Then you send it back down. It stays fairly hot because the Earth is a good insulator (绝热体).

“Unlike above-ground tank-based water or ice storage systems, ATES will not need space. It’s also more efficient and can support larger communities in cooling or heating than traditional geothermal heat pump systems that rely on heat moving with the underground soil,” added co-author Hong Tianzhen.

A major beneft of ATES is that it will become more efficient as weather becomes more extreme in the coming years due to climate change. The hotter summers and severer winters could increase the amount of free thermal energy that can be stored with ATES. “It’s very much a realistic thing to do and this work is really about showing its value,” said Perera. “This technology is ready to go, so to speak. We just need to do it.”

4 . Back in 1973, out of concern that many of American native plants and animals were in danger of extinction, Congress passed the Endangered Species Act. The law allows the government to decide species as either “endangered” or “threatened”. Once plants and animals are on the list, they can’t be harmed or harvested, and their living places can’t be changed or damaged in a way that kills, injures or weakens their ability to breed (繁殖), feed or perform other functions necessary for existence.

While environmentalists have thought the law is of great importance in history, mining and the agribusiness (农业综合企业) interests don’t think so. They argue that when an endangered animal is found on public land, the use of the land is strictly controlled, which can prevent farming, and other business use of the land. So, the recent US government has sought to change the way that the law is applied to reduce what it considers overprotection for threatened species.

But a study published in the journal PLOS ONE in January revealed that researchers looked at 31 different populations of ocean animals, and that they found that 78 percent of the mammals (哺乳动物) and 75 percent of the turtles increased their population size after receiving protection under the Act. What was even more impressive was that the number of Hawaiian humpback whales increased from just 800 in 1979 to more than 10,000 in 2005.

“We should celebrate the Act’s track record of reducing the harm from water pollution, overfishing, beach habitat loss and killing. Humans often destroy ocean ecosystems(生态系统), but our study shows that with strong laws and careful administration, we can also help them make a comeback.” said Shaye Wolf, a researcher of the Center for Biological Diversity in Tucson, Arizona.

6 . A couple has recently placed their garbage can out for collection for the first time in 14 months, all thanks to their recycling skills. Richard and Louise Arnold have established such an effective routine that they only need to put their garbage can on the side of the street once a year.

Louise explained that making small monthly changes in her life has resulted in her family producing very little waste. She said, “It’s not as difficult as you might think if you start with small steps. We began with soap, switching from bath cream to natural soap without packaging. These bars are large enough that we cut them in half, using one for the sink and the other half for the shower. It’s both cost-effective and environmentally friendly.”

“So it’s actually quite easy. Just go around your house and think of little things you can do gradually, and you’ll start noticing the difference,” Louise added. Currently, the couple takes recyclable waste to the tip, donates clothes to charity shops, and brings soft plastics and batteries to a shop that accepts them.

In 2017, the couple established No Waste Living, which initially started as a weekend stall at the local market and has since developed into a website. Louise regularly writes a newsletter for her hundreds of subscribers. They also started selling eco-friendly products, ranging from non-chemical household cleaning and washing solutions for a “less toxic home” to bamboo washing-up brushes. Louise mentioned, “I started No Waste Living because I wanted to show our achievement s and lead by example.”

Although the family occasionally faces criticism, Louise remains determined. She said, “The main point of contention(争论) for people regarding new waste rules is having to drive their waste to a recycling center, which adds to their already busy lives. However, in the long run, you will create more space in your home, save money, and spend less time dealing with garbage cans.”

7 . Lightning (闪电) is a beautiful and inspiring phenomenon, but it can be deadly. Over the past 30 years, lightning has killed an average of 67 people per year in the United States alone.     1     . Follow these steps to safety the next time there’s fire in the sky.

Find shelter immediately

If you find yourself caught in a lightning storm, never stand under a tree, and avoid being close to power lines as they’re both excellent conductors (导体) of electricity and could potentially cause death, if not serious injury.     2     . It’s the key to minimizing danger.

Watch out for dangers

Windows provide a direct path for the lightning to travel. Keep windows closed, stay away from them and try to stay within inner rooms of the structure.     3     Using a landline phone is the main cause of lightning-related injuries. Lightning can travel into the home from through any material that conducts electricity. This includes landlines, electrical wiring, and plumbing.

    4    

Being near water is extremely dangerous during a lightning storm, so move away from the body of water. If you are fishing, swimming or on a boat, get out of the water immediately and hurry back to the bank.

Stay inside

Stay inside at least 30 minutes after the last strike. Don’t go out just because the rain is starting to let up. There is still a significant risk of lightning strikes from a departing storm.     5     .

Lightning is dangerous but you can minimize your risk. The advice is simple: increase the awareness of avoiding danger and master proper knowledge to protect yourself from a thunderstorm.
