Clean Fossil Fuel Electricity
Renewable energy sources like wind and solar power are getting cheaper all the time and are, in many places, competing head to head on price with traditional fossil fuel generation. The ultimate goal is to replace polluting energy sources entirely, but even under the most optimistic scenarios, fossil fuel plants aren’t just going to disappear very quickly.
A Floating Wind Farm
The world’s first floating wind farm is being built 15 miles off the northeast coast of Scotland. The Hywind pilot park, expected to come online late next year, will generate enough power for 20,000 homes. The location will take advantage of average local North Sea wind speeds in excess of 20 miles per hour.
Greener Friendly Skies
In March, United Airlines began using a new biofuel for flights between Los Angeles and San Francisco. The fuel is a renewable product called Honeywell Green Jet Fuel that can replace up to half of the petroleum jet fuel used in flight without any changes to the aircraft technology and it meets all current jet fuel specifications.
Pulling Water From Air
As droughts have become more commonplace, researchers are looking at natural systems for effective ways to capture water from the air. A team from Harvard University has drawn inspiration from three different organisms to develop a better way to promote the condensation and transportation of water droplets.
Global Water Scarcity
Water is a simple chemical compound containing two hydrogen atoms and one oxygen atom connected by covalent bonds. It covers 71% of Earth’s surface and is vital for all forms of life. Despite its abundance, water that is safe for drinking is globally in short supply.
Drones And Wildlife Preservation
We hear more and more about drones these days. There is plenty of controversy about their use in warfare. Drones are also used to snoop on construction projects. Drones are spotted at the beach being used as high-tech toys. And drones are becoming a powerful tool in wildlife protection.
Natural Geoengineering
The term geoengineering has started to appear in discussions about how to combat climate change. Mostly, it is used to describe using technology to tinker with the global environment, for example, by artificially enhancing the atmosphere’s ability to reflect the sun’s rays back out into space and thereby cooling the planet.
Keeping Up With Light Bulbs
Light bulbs entered people’s lives in the 1880s. Tungsten filament lightbulbs have been around for about 100 years. Fluorescent lamps were invented in the 1920s. These two mainstays dominated most lighting applications for most of the twentieth century.
Turning Air Into Fuel
There is a global effort underway to combat climate change. The carbon dioxide in the atmosphere is the primary culprit. As a result, there are two things to do about it: reduce the amount of CO2 we are dumping into the atmosphere and try to remove some of what is already there.
British Columbia’s Carbon Tax
The recent Paris summit on climate change produced a global treaty to reduce greenhouse gas emissions. There are multiple strategies to reduce emissions including both technological and economic ones.
Preservatives
Augmenting food with preservatives is not a recent practice. For thousands of years, we have canned fruits with sugar, preserved meats with salt, and pickled vegetables so that they could keep in hot humid environments.
Clean Energy And The Internet
A number of large Internet companies are being very proactive in the area of clean energy. Companies like Google, Facebook, and Apple have invested billions on green energy solutions. This isn’t just good citizenship and good publicity for progressive companies, it is an essential part of the global effort to reduce greenhouse emissions.
Community Solar On The Rise
Most Americans are bullish on solar power. However, the majority of Americans are unable to install their own rooftop solar system because either they don’t own the place where they live or because their home is unsuitable for installing solar panels for one reason or another.
The Power Of Exercise
Many people often complain about not having enough time to exercise. But what if exercising for one hour could power your home for twenty-four hours? Would that be enough motivation?
Storing Heat From The Sun
We are all familiar with the solar panels that cover an ever-growing number of rooftops as well as large arrays in so-called solar farms. These photovoltaic systems turn sunlight directly into electricity. But they are not the only way to make electricity using the sun.
Climate Opinions
An international poll of over 45,000 people in 40 countries looked at opinions about climate change and the need to curb greenhouse gas emissions. The results are quite interesting.
Ocean Energy Report Card
Most of the world’s activity in renewable energy is focused on solar and wind power. The use of both is expanding rapidly.
Solar Powered Water Purification
Solar energy has made a difference in the lives of refugees from natural disasters and political unrest as well as people in remote corners of the world who don’t have access to modern technology. There are various solar-powered lamps, chargers, and cookers that have been provided to countless thousands of people around the world.
