A Better Way To Make Hydrogen
There is a great deal of interest in developing cost-effective, energy-efficient and environmentally-friendly ways of producing hydrogen. If hydrogen-powered vehicles are to catch on, it is essential.
Geothermal Power For LA
Los Angeles has a tremendous thirst for electric power and is always trying to find new sources. On December 1, the Los Angeles Department of Water and Power began buying all the power generated by the brand-new 24 MW Tungsten Mountain geothermal power plant located in Churchill County in Nevada’s Great Basin region.
Advantages Of Plug-In Hybrids
Plug-in hybrid vehicles are ones that can run both on electricity provided by a power outlet as well as on gasoline. There are many of them on the market these days built by quite a few car makers. But these vehicles have an undeserved reputation as being the fig leaf of electric mobility. Many environmental organizations and political decision-makers don’t consider them to be “real electric cars.”
Cryptocurrency And Climate Change
Bitcoin is a form of digital currency. Bitcoins aren’t printed, like dollars or euros. They are produced by people and businesses using computer software to perform the necessary complex calculations. A bitcoin is essentially a line of computer code that’s signed digitally when it goes from one owner to another. Bitcoin is the most prominent example of a growing category of money known as cryptocurrency.
Transportation And Greenhouse Gases
Power plants have been the biggest source of greenhouse gas emissions in the United States for more than 40 years. But the ever-changing picture of electricity production has changed that situation. According to new data from the government’s Energy Information Administration, transportation has now taken over the top spot.
Toyota’s Hydrogen Factory
Toyota is one of several automakers that are promoting hydrogen fuel cell cars – electric cars that get their energy from fuel cells rather than batteries. Fueling one of these cars is much like filling up the tank of a gasoline-powered car, except that the fuel in question is hydrogen.
The 100-Day Giant Battery
The Australian state of South Australia suffered crippling electricity outages in September 2016, which coincided with gale-force winds and flooding rains. The outages were triggered by storm damage to major transmission lines followed by wind farms disconnecting from the power grid.
Economics Of Solar And Wind Power
It is well-known that the cost of both solar and wind energy has been dropping dramatically in recent years. That trend is largely responsible for the rapid growth of both power sources. A recent study has revealed just how remarkable the economic progress has been.
Coffee Power
The residents of London are known for tea drinking, but in fact each of them consumes an average of 2.3 cups of coffee a day as well. But now, it won’t just be commuters that are running on coffee in the morning. London buses will in part run on oil produced from coffee grounds.
Transparent Solar Panels
It is now commonplace to see solar panels on the rooftops of homes and businesses. There are more than a million solar homes in the US alone. But a new generation of see-through solar technology has the potential to also turn the windows of buildings and cars, as well as other glass-coated objects, into electricity generators.
GM And Fuel Cells
There has been a spate of announcements from major car manufacturers in recent times detailing their plans to electrify their future vehicles. General Motors recently announced its “path to zero emissions” plan which includes the introduction of at least 20 electric vehicles by 2023. They are joining Volvo, Volkswagen, Toyota and others in making such an announcement.
Energy From Evaporating Water
Researchers at Columbia University have demonstrated a potential new energy harvesting technique based on the natural evaporation of water. Every day, vast amounts of water evaporate from the surfaces of lakes and rivers, a process powered by the heat energy of the sun. The amount of energy involved is enormous but generally speaking is not something we can tap into.
An Ancient Way To Store Energy
Firebricks, which are bricks designed to withstand high heat, have been around for more than 3000 years. The Hittites used them to line iron-smelting kilns. They are simply bricks made from clays that can withstand much higher temperatures than ordinary bricks.
The End Of British Coal
In the 19th century, Britain produced 80% of the world’s coal. Britain was the dominant global power in the industrial revolution with its giant blast furnaces, steam locomotives and steam ships. And with advent of the electric age, coal once again was the power source of choice. Even as late as the 1970s, Britain got 80% of its electricity from burning coal.
More Power From The Sea
The Okinawa Institute of Science and Technology or OIST has been working on ways to generate electricity from the ocean for five years. Their initial project, known as “Sea Horse” uses submerged turbines anchored to the sea floor that convert the kinetic energy of sustained natural currents into useful electricity, which is then delivered by cables to the land. The project has been successful and OIST is now planning the next phase.
A Giant Solar Thermal Plant For Australia
A project planned for sunny South Australia will be the world’s largest single solar thermal power plant when it comes on line in 2020. The Aurora Solar Energy Project will have a capacity of 150 MW, which is enough to supply 90,000 people with electricity.
