A SOBER LOOK AT ELECTRICAL CHOICES FOR BELIZE POWER SUPPLY

 A SOBER LOOK AT ELECTRICAL POWER SUPPLY FOR THE SMALL COUNTRY OF BELIZE.  THIS IS REALITY.



Reference to below.
 
That is not true.
 
Thermal power plants are highly flexible and can respond to all load demands.  I should know I operated them for enough years.
Hydro can come from stopped to full load in two minutes and are very flexible. Is that quick enough.!!!
Gas turbine are also highly flexible.
 
Diesel generators on the grid system are usually very small compared to thermal power plants.
 
Wind generator are totally unreliable and inconsistent, and only attain an average of 20-25% of their capacities.
 
As for tuning them off. Your flat out getting them to turn on. And certainly not because of nuclear power.
Where does power come from at night-obvious, thermal power generation, hydro, or nuclear if it is there,
Only 1.5% of Australia and 2,3% of the USA is renewable energy in the form of wind or solar.
Thermal power has increased 94% since 1993.
And no they do not run at constant base load. Some units are selected for load control whilst the larger units stay at max load but they also can do load control if required. A matter of the most efficient.
 
Hydro is the ultimate power generation as long as you have the water. See China power-Hydro- 3 gorge dam and 21 other schemes.
 
 
I might add Fukishima was 40 years old and was supposed to be closed down due to old design and age three months before.
Modern nuclear power stations are far safer and better designed.
I believe the power for the future LFTR nuclear reactors, tidal and wave generators on a smaller scall, but some time in the future.
 
Australia and the USA  have enough coal to last 380 years without including unlocated sources...
 
The cheapest power- Hydro, then nuclear, then  coal fired, then gas. Geothermal is cheap but very limited to very small areas. Mainly some parts of NZ and the USA.
Wind generation and solar farm array generation is expensive for the kilowatts generated, installation cost and maintenance costs.
 
, Hydropower also has
>> significant environmental impact, in terms of loss of land area, and
>> changes to natural water flow patterns, which can have a very significant
>> environmental impact.
 
See three gorge dam. Any roads or airports you build etc. etc. It also creates excellent lakes and water sports. There is NO environmental impact but certainly is from wind generators. Research those people who live near them. They are being driven mad by the droning noise.
 
The amount of feed power from solar panels into the main grid system is equal to a teaspoon in a 200 litre drum. Tottally insignicant, expensive and a pain in the backside to the power system.
 
As for pricing I believe since the power generation and distribution companies were privatised we are being ripped off more and more and will get worse.
 
Please pass this on to all to correct the misconceptions.

Here's how to cut your electric bill by 75%:

Want to know how to easily produce all of the renewable energy you could ever want right at home?

And you will be able to make your home totally immune from power outages, blackouts, and energy grid failures
so even if everyone else in your area (or even the whole country) loses power…you won’t.
