The country is still heavily reliant on coal, but this could change in the years ahead.

Tesla Semi: Elon Musk says time to bring electric trucks to volume production
Elon Musk has said that “it is time to bring” Tesla Semi electric trucks to volume production in a memo to all Tesla employees.
In a new email to employees last night, Musk that he wants to go “all out”:
“It’s time to go all out and bring the Tesla Semi to volume production. It’s been in limited production so far, which has allowed us to improve many aspects of the design.”
New Generation of Lightweight, Flexible Solar Cells and Display Screens Using Transparent Graphene Electrodes
New roll-to-roll production method could enable lightweight, flexible solar devices and a new generation of display screens.
A new way of making large sheets of high-quality, atomically thin graphene could lead to ultra-lightweight, flexible solar cells, and to new classes of light-emitting devices and other thin-film electronics.
The new manufacturing process, which was developed at MIT and should be relatively easy to scale up for industrial production, involves an intermediate “buffer” layer of material that is key to the technique’s success. The buffer allows the ultrathin graphene sheet, less than a nanometer (billionth of a meter) thick, to be easily lifted off from its substrate, allowing for rapid roll-to-roll manufacturing.
Tesla investor Ron Baron expects exponential growth for Elon Musk’s car company and SpaceX
Billionaire investor Ron Baron believes there’s still plenty of room for growth for Elon Musk’s Tesla and SpaceX companies.
Baron said Tuesday morning on “Squawk Box” that he believes “there’s 10 times more to go” with Tesla. He also said SpaceX, a privately held company, will grow by a multiple of 20 in the next 10 years. He previously predicted similar growth for Tesla.
Nio might have figured out battery swap for electric cars as it completes 500,000 swaps
Over the years I have been covering electric vehicles, I’ve seen several companies attempt to add value to EVs by using swappable battery packs.
The idea is that if charging takes longer than refueling a tank of gas, we could just swap a battery pack for a fully charged one.
A startup called Better Place built its entire business model around it and went bankrupt.
Scientists Create Prototype That Generates Electricity From Shadows
It sounds like something from a sci-fi movie, but the newly revealed Shadow-Effect Energy Generator (SEG) is a real prototype device. The fascinating concept could help us to transform the way renewable energy is generated indoors.
The SEG uses the contrast between darkness and light to produce electricity. It’s made up of a series of thin strips of gold film on a silicon wafer, placed on top of a flexible plastic base.
Whereas shadows are usually a problem for renewable solar energy production, here they’re actually harnessed to keep on generating power. The technology — which is cheaper to produce than a typical solar cell, according to its developers — produces small amounts of power and could be used in mobile gadgets, for example.
Russia declares state of emergency after Arctic oil spill
Russian President Vladimir Putin of Russia declared a state of emergency in a region of northern Siberia after a huge oil spill last week turned a river crimson. It is threatening significant damage to the Arctic region. [ 317 more words ].
Norilsk Nickel is the world’s largest producer of platinum and nickel.
The company, along with the Russian Emergency Situations Ministry, dispatched hundreds of personnel to clean up the spill. So far, Norilsk Nickel said they had managed to gather up only around 340 tons of the oil.
Barges with booms could not contain the slick because the Ambarnaya River was too shallow. Some media is calling the spill, “Russia’s Exxon Valdez.” In that 1989 incident, more than 37,000 metric tons of crude oil were spilled in Alaska.
A look at Tesla battery degradation and replacement after 400,000 miles
In this new installment of our series on the highest-mileage Tesla Model X (and one of the highest mileage EVs in the world), we look into battery degradation and replacement on a Tesla with over 400,000 miles.
Earlier this year, I bought one of the cheapest and most high-mileage Tesla Model X vehicles ever.
With over 400,000 miles (650,000 km), it’s one of the highest-mileage electric vehicles in the world and serves as a great case study for the longevity of electric cars, in general, and Tesla vehicles in particular.
