The CREE LED bulb most common is a direct replacement... can't tell the difference by glancing at the bulb... A19 I believe... plus coated so shatter resistant.

I still use the older bulbs for all the reading lamps and the dimmers that won't take the newer bulbs.

I have a really hard time finding LEDs that will work in enclosed fixtures - and we have five or six fixtures like that. I can still find some incandescent bulbs in PA. This is making me think I should buy tons of them next time I see them.

The Great Value ones at WalMart say they can be used in fully enclosed fixtures.

Household light bulbs do not have a substantial impact on electricity usage. The big culprit is compressors and pumps, particularly air-conditioning and refridgeration.

There is no water shortage on earth. The problem we have is with the distribution of water. Some parts of the earth do not have enough clean fresh water available to support the number of humans living there. Really the problem is with the distribution of humans. Most of Canada, for example, is full of water but empty of humans.

Few realize how serious the water problem int he Southwest is. If technology does not create a solution soon, some states will eventually have to be vacated. A few people can stay, but many areas cannot get enough water to support the growing population. Phoenix is probably the biggest problem. Conservation cannot save Phoenix. Either they find some new source of water or they need to decrease its population substantially, Instead, the population is growing like mad. However many states will be impacted. NEw Mexico, Southern California, parts of Texas, Nevada. . .
Water is used. It is not all returned through rain. How much we use and for what matters.

Regardless of more obvious culprits (fracking and nuclear energy plants use tremendous amounts of water), it all counts. Creating power, watering lawns, taking too long showers, using inefficient appliances and toilets, it all adds to the bill.

The first and most effective method of energy management is to use less. Lighting is a significant energy use issue. Bulbs are used by billions of people on the planet, so how they work and how we dispose of them matter.

Regarding water, you are not looking at the big picture, which is why scientists do not agree with you that the planet is not already suffering a water shortage, with worse to come if we do not find a way to turn things around.

You're right about Phoenix. When we left Phoenix well over a decade ago, Arizona and Nevada had already started fighting over water to power their states.

We use 12 kWh daily average year round with ancient applicances and a 1950 home of 2300 square feet.

The SF Bay Area micro climate is extremely mild...
It really depends on where you are in Washington, which utility you have to pay. Seattle City Light is a public utility and it avoided the WPPSS debacle (where investors got away with sticking ratepayers with their investment losses). Seattle City Light, being a public utility, is non-profit and its customers didn't have to pay for WWPPSS losses. When we were in Seattle, we had very good rates. However, when we moved to Olympia and were stuck with the for-profit Puget Power, which had jumped on the WWPPSS bandwagon and lost, plus needed profit, we had substantially higher rates.

Back in the day, thanks to the federally subsidized dams, the Pacific Northwest enjoyed super cheap electricity. Since then, though, we discovered the environmental damage our dams were causing and that no source is infinite, so electricity isn't as cheap as it used to be no matter what utility is producing the power. Still, for-profit utilities cost ratepayers more.

that gives all these home centers and small hardware stores access to product without doing hundreds of thousands of dollars in those products so as to be a direct distributors ..

i spent 40 years in the electrical wholesaling business . while i sold quite a bit of lighting my expertise is in motor controls and variable frequency drives .
That's interesting.

My spouse would have a grand old time talking with you! (<:

Now I doubt I run the mill 10 hours total in a year...

Bridgeport NC J-head with 1 hp motor... Lathe 2 hp motor... rotary Converter same hp for each.

I love making do with what I have on the cheap... so going LED coming from me is quite a statement... did I say how much I love CREE bulbs... soon to be 3 years and no issues.
I know nothing about motors, but that was amusing, and I totally relate to the first and last sentences.

Default When it comes to necessities for life

they originally tried to stop us from connecting our gear in to their electric service . today they are much more liberal about it . but they still use demand meters and power factor surcharges to make sure you do not save to much .

a lot of what i did is to design the control panels that controlled the speed of the water pumps and fans in a facility . being able to cut the speed of a pump in times of low demand has a huge energy savings . if you cut the speed in half on what we call variable torque loads like fans and pumps you don't half the energy . you reduce it by a lot more . a 10hp motor acts like a 2-1/2 hp motor .when you cut the speed by 1/2
Perhaps when it comes to absolute necessities for life, there is an argument to be made for removing the profit motive.
