ᐅ Electricity and Gas Caps – Interested in Some Numbers?

I don’t know if anyone else besides me enjoys analyzing consumption and numbers related to the electricity and gas price caps and their forecasts, so here is just an attempt:

Forecast: Electricity 2,400 kWh per year, consumption since 06/04/22 at 2,917 kWh
Forecast: Gas 20,000 kWh per year, consumption since 06/04/22 at 52.81 m3 (cubic meters) → converted with factor 10 results in 528.1 kWh

The following is for those who want more detailed information:
-------------------------------------------------------------------------
Single-family house (Leipzig district) with underfloor heating / tiles throughout
Built according to energy saving regulations (gas condensing boiler plus solar thermal system)
Approx. 139 sq m (1,495 sq ft) of living area
Residents are two adults, no children, home all day
Moved in early August 2022
Electricity and gas meters have been running since about mid-June 2022
Until September 2022, supply was via temporary contract; since October 2022, basic supply
Special features: sauna (operated once a week using high-voltage power) and home brewing beer (about once a month)
Thermal final energy per sq m: 37.57 kWh/m2a – auxiliary final energy per sq m: 2.87 kWh/m2a – primary energy per sq m: 46.5 kWh/m2a

Edit: Unfortunately, I was no longer able to change the title to "...-price cap," which would be more accurate.

How was it again with owners of oil heating systems (and pellet stove owners)? Do they also receive any support? (1.70€ per liter is definitely not cheap and a real problem for low-income households)

We are currently at
- Basic and backup gas supply: 13.32 cents gross per kWh (basic fee 6.69 euros gross)
- Basic and backup electricity supply: 32.21 cents gross per kWh (basic fee 12.09 euros gross)

I realize that I still want to learn and understand more about energy supply, as I am surprised that the unwanted gas is cheaper than the preferred electricity.

However, if you produce 3-5 kWh of heat from 1 kWh of electricity using a heat pump, you will notice how expensive gas actually is. At a factor of 3, gas is 30% more expensive; with a highly efficient ground-source heat pump achieving a factor of 5, gas is more than twice as expensive.

I’m not an expert, but shouldn’t the efficiency of the gas heating system also be taken into account for a fair comparison? That would likely make the difference even more favorable towards the heat pump.
For the heat pump, efficiency is already included in the factor used to calculate this, right?

My daily newspaper states, "Scholz also announced relief measures for people heating with oil or wood pellets."

Gas heating systems have an efficiency of around 100%, so it does not need to be considered separately.
