Solar Rooftops Looking Better Than Ever
The price for installing solar panels continues to get lower and lower as volumes increase and technology improves. There are also more ways than ever to get solar installed with leases and other creative financial arrangements.
Recycling CO2
The X Prize Foundation provides financial incentives for innovative solutions to various technical challenges. Topics have ranged from developing spacecraft to trying to create a real-world version of the Star Trek tricorder. Last year, the foundation launched a $20 million challenge to come up with technologies by the year 2020 that turn carbon dioxide captured from the smokestacks of power plants into useful products.
Making It Rain
It seldom rains in the United Arab Emirates. Some areas of the UAE receive less than five inches of rain annually, and often little to none at all during the summer months when temperatures can climb above 110 degrees Fahrenheit. These conditions have led to water security concerns particularly in Dubai, a blossoming international destination, as well as in rural, farming communities.
Mandatory Solar In San Francisco
California leads the nation in the use of solar energy with well over half the country’s solar electric capacity. The state is the home of several of the largest thermal solar generating plants in the world and between those and multiple utility-scale photovoltaic plants, California utilities get more than 5% of their power from the sun.
Electric Car Boom
The introduction of the Tesla 3 and the 400,000 advanced orders for the vehicle have put the spotlight on electric cars recently. But despite all the buzz, electric cars are sill only a tiny piece of the US car market: about 0.66 percent last year.
Electric Buses And Trucks
We hear a great deal about electric cars these days. Will people buy them? Are they worth it? And, of course, there is the tremendous buzz surrounding Tesla’s forthcoming moderately-priced car. But there is also lots of activity in electrifying larger vehicles, including garbage trucks, city buses, and medium-sized trucks used by freight companies like FedEx.
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.
Human-Caused Earthquakes
Oklahoma has had its share of disasters over the years. It has seen tornado outbreaks, massive wildfires, huge dust storms and even onslaughts of tumbleweeds. But one thing it was not known for is earthquakes.
Growing More Food On Less Land
There are predictions that the world’s population could reach 10 billion by the year 2050. Whether population growth can be slowed down enough to prevent this remains to be seen. Regardless, it is clear that we need to figure out how to feed many more people than we have today and we are not even doing that good a job of feeding the current population.
Scottish Coal
The Scottish government has an ambitious plan to meet 100 percent of its demand for electricity from renewable sources by 2020. Like much of the world, Scotland has produced significant amounts of its electricity by burning coal for more than 100 years. But no longer.
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.
A Wind-Solar Streetlight
The Caribbean island nation of Grenada has installed a wind and solar powered off-grid streetlight. An Irish company called airsynergy has developed the underlying technology which it calls a Remote Power Unit or RPU.
Old Car Or New Car?
Every few years many of us face a big decision: is it time to buy a new car? The trusty vehicle that has carried us so well has gotten too rusty to pass inspection or too old to assure us of its continued reliability. What vehicle choice is best for the environment?
Tomato Energy
People continue to find new ways to generate energy from unusual sources. A team of scientists at several universities recently reported on a new fuel cell that uses tomato waste left over from harvests in Florida.
Biodegradable Bottles
Plastics are the ubiquitous workhorse material of the modern economy. Their use has increased 20-fold in the past half century, and production of plastics is expected to double again in the next 20 years.
Coal And Water
We recently highlighted how safe drinking water is in short supply. According to research published in the journal Science Advances, at least two thirds of the global population – more than four billion people – live with severe water scarcity for at least one month every year. And 500 million people around the world face water scarcity all year.
Long Island Wind
The Interior Department has recently defined a “Wind Energy Area”, consisting of about 81,000 acres, located 11 miles south of Long Island. The designation is a first step to opening up the acreage for large-scale, competitive wind energy leasing through the Bureau of Ocean Energy Management.
Old-School Companies And Renewable Energy
The biggest Internet companies have been embracing renewable energy for years now. The company that bought the largest amount of clean energy last year was Google, which has three times the renewable capacity of the next biggest user. Other familiar names in the top ten companies in total wind and solar capacity include Amazon, Facebook, Microsoft, and Apple. These companies have been ahead of the pack in looking for sustainable ways to meet their substantial energy needs.
