I thought Electric Cars Were the Future. I Changed my Mind.

I thought electric vehicles were the future of transportation. Not so much because they're clean, but because many car enthusiasts love them for their powerful acceleration. However, it's becoming increasingly clear that the necessary upgrades to the electric grid aren't going anywhere near fast enough to get the transition done according to plan. This is why I believe now we'll likely see a shift to hybrids in the near future.

Heat Pumps Finally Make Sense -- Maybe

Most buildings across the globe are heated with gas and oil despite heat pumps being a much more energy-efficient alternative. While some countries have been keen on adopting them, others have been slow on the uptake. Why have some countries been hesitant to push the technology? Could a new upgrade to heat pumps make them a more viable heating option? Let’s have a look.

Solar arrays better than trees for climate, study says

What is better, planting trees or covering the same area of land with solar panels? A group of geoscientists from Israel just looked at this, and they say that solar panels come out way ahead. Let's have a look at what the paper says.

The true cost of nuclear power

Out of the many bad arguments against nuclear power, there are two good arguments: It's too expensive and the power plants take too long to build. But are they true? And if so, why is it that nuclear power is so slow and so costly? That’s what we’ll talk about today.
