Electricity

Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell’s equations.

Why Are Energy Prices So High? Some Experts Blame Deregulation. – The New York Times

When California, New York, Texas and other states began deregulating their electricity markets in the 1990s, officials promised that those changes would foster competition and make energy more affordable.

But it hasn’t worked out that way.

Average retail electricity costs in the 35 states that have partly or entirely broken apart the generation, transmission and retail distribution of energy into separate businesses have risen faster than rates in the 15 states that have not deregulated, including Florida and Oregon. That difference has persisted for much of the last two decades or so, including in the last year, when energy prices increased worldwide after Russia invaded Ukraine.

On average, residents living in a deregulated market pay $40 more per month for electricity than those in the states that let individual utilities control most or all parts of the grid. Deregulated areas have had higher prices as far back as 1998.

Watt hours!

Um. 4400 mAh is just a self promoting way to say 4.4 amp hour.

And with a 3.7 volt lithium ion cell that works out to be 16.3 watt hours. But that doesn’t sound that impressive.

So, What Exactly Is Building Electrification? | Greentech Media

Buildings were first electrified nearly 150 years ago. So, why is it that “building electrification” is now among the energy industry’s most popular buzzwords?

Most buildings run on multiple fuels. They use electricity to power lights, refrigerators and electronic devices. And they consume fossil fuels such as natural gas or propane to power furnaces, boilers and water heaters.

That persistent reliance on fossil fuels makes buildings one of the largest sources of planet-warming pollution. In the United States, buildings account for roughly 40 percent of the country’s energy use and greenhouse gas emissions, and nearly half of all homes rely on natural gas as their primary heating fuel.

Isolation transformers are wonderful things when working with high voltage devices with the case open and power on, like when trying to find a blown capacitor in a television. Greatly reduces your chances of dying should you touch the hot side of things, as hot isn’t referenced to ground – only the neutral on the transformer.
 
If you don’t put both hands on the device, and there is no path through your heart from hot to neutral, chances are good that you live, although you could still get burned on a hand if it’s a path between hot and nuetral in your device.
