Simple only get a watt meter and go to the fuse box, open unscrew it and measure one by one the fuse, if found the one using a lot watt, just turn it off and see which appliance turn off.

just get something like this and plug it in on the appliance u want to monitor.

No point screwing tnb if it costs more.
What typical houses uses 1500 kwh a month?
Single storey house like 2 Ac at night, also only use 600 kwh.

Hydrogen also not clean because you crack hydrocarbons with steam to make it.

Double storey terrace easily achievable if 3 aircons running day and night due to whole family WFH

Electricity power lost

Different power is lost at different stages
1-2% of energy is lost during the step-up transformer from when the electricity is generated to when it is transmitted.
2-4% of energy is lost in the transmission lines
1-2% of energy is lost during the step-down of the transform from the transmission line to distribution.
4-6% of energy is lost during the distribution
So, the average loss of power between the power plant and consumers ranges between 8-15%.

Natural gas combined cycle power plants play an important role in the construction industry. These power plants are the most efficient power plants operating on the power grid with an efficiency between 45% and 57%.

Power generation in Peninsular Malaysia in 2014 came from natural gas (53.8%), coal (35.3%), hydropower (10.3%), distillates (0.6%) and MFO (0.04%).

So the energy loss from energy sources to EV is 100 * 40% (assume average power plant efficiency) * (100-12)% * 90% (assume ev charge efficiency) = 31.68%


ICE car engine efficiency is around 35%
ICE car mileage per kWh is 40% less efficient than EV car (EV car consumes much lesser energy at traffic jam, EV car can recover energy from braking)
Petrol distribution lost let assume is 10%

Energy loss for ICE car is 100 * 35% * 90% * 60% = 18.9%


Not to mention ICE car produce nitrogen dioxide and other toxic gas direct to populated areas.

Obviously you don’t fully understand how hydrogen is produced, what you mentioned is grey hydrogen production

As of 2020 95% of hydrogen production by the way I described.
You want to ramp up also going to take a long time and it is a chicken and egg situation.

Nothing is stopping you from doing the battery thing. Easily available now. Just need to pay more for battery to screw TNB.

Why don’t you look at the bright side?

Do you know hydrogen can be considered as battery? For those solar and wind power plant that produces excessive energy, excessive power can be used to produce hydrogen, and hydrogen is like petroleum which is transportable energy storage.

Wind and solar energy is not stable power source, we need energy storage to store excessive energy and can immediately use the energy storage when energy is needed.

Energy from fossil has to be reduced as could as possible, it is long process to eliminate fossil fuel, but it has to be done. During this long process, diverse energy sources are the key to implementing carbon free energy.

A very leaky battery, you need 13% of the energy to compress it and then when it is liquid you can lose up to o% by evaporation.
Hydrogen ain’t perfect and did I mention it was explosive?

What is the point of doing that?
Do you know how solar inverter work ?

You have full of negative thoughts, the world will not progress if there are many people like you.

Hydrogen storage is as safe as petrol storage, Japanese has proven it, and you will see more and more hydrogen powered vehicles in near future

No
I’m all for decarbonising but I don’t think hydrogen is the way forward. We need a cheap and green battery technology and we need it fast.
Not recognising the drawbacks of hydrogen and being wedded to one particular technology is also anti progressive.

For static applications, just use mechanical energy storage like flywheel (0.5Jw^2) or gravity battery (mgh). No need hydrogen or electrochemical batteries. For automotive applications, the way forward could be to have embedded wireless power transfer from the road to vehicle. If you could get about 50 kW, it should be more than enough for most vehicles travelling on highway speed. Smaller battery pack needed only for travelling on roads away from the highway with embedded wireless power.

For me, I rather have cyborg horse that can gallop at 100 km/h with unlimited stamina... Or for someone to figure out how to use quantum tunnelling for macroscopic teleportation... Or maybe some alien civilization will donate their warp 9 alcubierre drive so we all can migrate out of this planet...

So u don't feed your unclean energy back to the grid ba

I recall 2 years ago when I used China inverter we were told not to connect directly to our grid as it can cause problem

"Unclean Energy" , what is it.





so tens of thousands of solar panel inverter users in Malaysia is causing problem to the grid?

That is not a norm in most household 😅😓

Open 3 ACs night and day? Fulamak

Better increase own battery station capacity store energy for ur own liao haha
