Antigravity water transport system inspired by trees

Efficiently moving water upward against gravity is a major feat of human engineering, yet one that trees have mastered for hundreds of millions of years. In a new study, researchers have designed a tree-inspired water transport ...

New approach to energy strategy accounts for uncertainty

Many countries—including Switzerland—are developing an energy strategy to meet various objectives such as reducing reliance on fossil fuels, cutting CO2 emissions and promoting the energy transition. That means governments ...

The competitive benefits of a modern energy system

As the EPA retreats from the Clean Power Plan's goal of reducing greenhouse gases and promotes President Trump's 19th-century coal-fired energy policy, states like New York and California are aggressively modernizing their ...

New look at old data leads to cleaner engines

New insights about how to understand and ultimately control the chemistry of ignition behavior and pollutant formation have been discovered in research led by Sandia National Laboratories. The discovery eventually will lead ...

Chile tests floating solar panels to power mine, save water

A floating island of solar panels is being tested in Chile as a way to generate clean energy and reduce water loss at mine operations, a cornerstone of the Andean country's economy that uses huge amounts of electricity and ...

Nature-inspired antibacterial metals

From aviation to medicine, various sectors are increasingly using materials that mimic the lotus plant, whose leaves have self-cleaning properties. Thanks to the bumpy surface structure covered with tube-shaped wax crystals, ...

Green energy

Green energy is the term used to describe sources of energy that are considered to be environmentally friendly and non-polluting, such as geothermal, wind, solar, and hydro. Sometimes nuclear power is also considered a green energy source. Green energy sources are often considered "green" because they are perceived to lower carbon emissions and create less pollution.

Green energy is commonly thought of in the context of electricity, mechanical power, heating and cogeneration. Consumers, businesses, and organizations may purchase green energy in order to support further development, help reduce the environmental impacts of conventional electricity generation, and increase their nation’s energy independence. Renewable energy certificates (green certificates or green tags) have been one way for consumers and businesses to support green energy.
