Tesla and SolarCity have just unveiled a new series of solar roofs that look almost indistinguishable from traditional ones, and are said to cost the same amount of money.

Wi-Charge is a long-range wireless charging system that lets you charge your device wherever you are in the room. With absolutely no cord necessary, the range can be up to 10 meters indoors. Wi-Charge uses infrared beams to deliver power. Devices just have to in Wi-Charge’s line of sight for it to charge. Although charging is slower than normal cable charging, it happens 24/7 without you even knowing that it is.

The system has been approved by the FDA and is expected to arrive to commercial public spaces in early 2018.

Self-driving cars exist today that are safer than human-driven cars in most driving conditions. Over the next 3–5 years they‘ll get even safer, and will begin to go mainstream.

The World Health Organization estimates that 1.25 million people die from car-related injuries per year. Half of the deaths are pedestrians, bicyclists, and motorcyclists hit by cars. Cars are the leading cause of death for people ages 15–29 years old.

Just as cars reshaped the world in the 20th century, so will self-driving cars in the 21st century. In most cities, between 20–30% of usable space is taken up by parking spaces, and most cars are parked about 95% of the time. Self-driving cars will be in almost continuous use (most likely hailed from a smartphone app), thereby dramatically reducing the need for parking. Cars will communicate with one another to avoid accidents and traffic jams, and riders will be able to spend commuting time on other activities like work, education, and socializing.

Attempts to fight climate change by reducing the demand for energy haven’t worked. Fortunately, scientists, engineers, and entrepreneurs have been working hard on the supply side to make clean energy convenient and cost-effective.

Due to steady technological and manufacturing advances, the price of solar cells has dropped 99.5% since 1977. Solar will soon be more cost efficient than fossil fuels. The cost of wind energy has also dropped to an all-time low, and in the last decade represented about a third of newly installed US energy capacity.

Forward thinking organizations are taking advantage of this. For example, in India there is an initiative to convert airports to self-sustaining clean energy.

Tesla is making high-performance, affordable electric cars, and installing electric charging stations worldwide.

There are hopeful signs that clean energy could soon be reaching a tipping point. For example, in Japan, there are now more electric charging stations than gas stations.

And Germany produces so much renewable energy, it sometimes produces even more than it can use.
