Wind Turbines / why pitch the blades instead of getting a larger generator?
« Last post by Ian on July 23, 2021, 11:53:17 AM »
Hi all

I'm a bit of a newbie in wind turbine technology, and I was watching one of these one-minute videos explaining wind energy topics (I can post the link but it's called Why do wind turbines purposefully decrease their efficiency?). The video explains that you pitch the blades in high winds in order to reduce power output and protect the generator from damage. So my question is, why don't you just put a bigger generator? As far as I know, it wouldn't be much more expensive (just a little heavier), and that would allow you to get more energy with the same blades, same gearbox, same tower, etc.

Or am I missing something?
General / Advice on heating and hotwater

Where can I discuss my options for efficient heating and hot water?

I have solar panels, an electric car and an economy7 tariff.  My heating is ancient storage heaters and the hot water was a gas boiler that has ceased to operate.
I would like to replace the heating and hot water so that I'm not using gas and it would be nice if I could make better use of the electricity generated by the solar panels which mostly just goes to the grid as I am at work in the day.

Its a one/two bedroom flat, with just one occupant. I only need enough hotwater to fill a sink, occasionally a bath. the shower, washing machine, dishwasher all just use cold water feeds and heat water electrically on demand. i only need enough heat to keep the chill of in the winter. Currently, the storage heaters heat all night, cool down during the day whilst I'm, at work and aren't much use in the evening when I need them. its also so wasteful to heat the house all day when I just need an hour in the morning and a few hours in the evening.

What would you do? Hot water tank with smart heater using excess solar PV? what about winter - can it use cheap rate electric at night? would the tank lose much energy throughout the day? How to Best heat the flat?  Modern storage heaters? Some system to store Solar PV from daytime and power heaters of an evening?

Or is your interest based solely on the technology side or the finiteness of fossil fuels? For me it's a mixture of all, but climate change is a huge deal to me, and I'm surprised it isn't seen as a larger public issue.
We do have rules, however, we can bypass those at any time if that means we can have something meaningful out of it."
General Discussion / Looking to change to a green career
« Last post by TeslaDoug on July 19, 2021, 05:07:24 AM »
30 something year old airline pilot here, looking to change careers. It may sound hard for some to believe, but I've completely lost my passion for aviation, was getting a little burned out, and then the COVID stuff zapped most of the rest of the joy out of it. Furthermore, I've always felt a discrepancy between my concern for the planet, and my occupation, which involves combusting a lot of hydrocarbons.

I obviously have some technical skillset and aptitude, some college and am trying to get an idea what areas of renewable energy might be a good fit for me. Being some kind of technician might be good, though I'm not currently fully able-bodied (cryonic foot and back pain). If I could somehow get into an occupation where I worked from home that would be ideal at this point.

I'm also in the states, couldn't seem to find an analog to this forum in the US, but I figure the industries and job requirements are similar on either side of the pond.

Anyway, and advance would be greatly appreciated!
There are many benefit for the people who want to use solar in the long run:

1. Reduces Air Pollution. Fossil fuels create a lot of pollutants.
2. Reduce Water Usage.
3. Reduces Dependence On Nonrenewable Energy Sources.
4. Improves Humanity's Health In The Long-run.
5. Helps Fight Climate Change.

Solar water heating systems usually cost more to purchase and install than conventional water heating systems but they benefits the user in the long run it is a good way to save some cost.
