The Most Polluting Industries In The World

pollutionScientists have been sounding the alarms about climate change for decades, but unfortunately we are still completely dependent on digging stuff up and burning it for our main sources of energy. The United States gets 39% of its energy from coal, which is ok from a national security standpoint until the acid rain makes our water undrinkable. Natural Gas pollutes 30% less than coal and the U.S. gets 27% of its energy from that source, but there are still significant pollution issues. And, of course, there is a threat of a meltdown, but mainly the radioactive waste is dangerous for 240,000 years.

People have been looking for alternative energy sources for decades, but progress in getting them installed means less than 15% of the energy produced in the United States comes from renewable or clean sources. Hydropower is the largest sector of green energy in the U.S., responsible for almost 7% of the power production. It is, however, not without its own issues- dams can endanger ecosystems, so hydroelectric power has to be done properly. Wind is an emerging energy sector at almost 4.5% of America’s power grid. Just one percent of power produced in the U.S. comes from solar or geothermal sources, though that number is always increasing with improvements in technology.

Transportation is one sector where small improvements in efficiency can have a huge impact. Increases in mandatory fuel efficiency have decreased air pollution since the 1970s. Continuing to increase efficiency will continue to improve the environment. Biofuels have also shown promise in decreasing pollution. Now many people are even driving hybrid electric and full electric cars. When powered with solar power they produce zero emissions, and even when they get their power from traditional sources they still pollute less than traditional internal combustion engines.

Thinnest and Lightest Solar Cell Produced

solarbubble

Researchers at MIT have successfully manufactured the world’s thinnest and lightest solar cell. This cell is so tiny that it could be placed on a soap bubble without popping it. That’s quite a feat and it also means that such cells could be attached to virtually any surface where they could then generate clean, renewable energy. (more…)

A Thermophotovoltaic Cell That Can Generate Electricity Even in the Dark

scientist

Claiming that a solar cell can produce energy even in the dark sounds a little like the beginning of a joke, but I assure you it is not so. A team of scientists from the Australian National University (ANU) and the University of California Berkeley (UC Berkeley) have successfully made a prototype of a device, which can become a part of super-efficient thermophotovoltaic cells. Such a cell could generate electricity even if it is not placed in direct sunlight. This cell would absorb infrared radiation and convert it into an electric current, and this can happen even in the dark. (more…)

These Greenhouse Lamps will Brighten Any Room

plantlight

It’s a sad fact that many city dwellers do not have a single plant in their homes, and this is more often than not because of a lack of adequate daylight coming into the cramped urban apartments. But the Kiel, Germany-based firm We Love Eames seeks to alleviate this problem with glass planters, which act as both greenhouses and lights at the same time. These planters are not only gorgeous to look at, but they also bring the possibility of growing your own veggies to urbanites living in apartments with small windows and no balconies. (more…)

Off-Grid Foot-Powered Washing Machine

machine

Washing machines use up a lot of energy and water, so having one when you’re striving for off-grid living is not a convenient option. But the so-called Yirego Drumi washing machine solves this problem. It is powered by a foot pedal and needs no electricity to operate. As such it would make a great addition to any sustainable home.
