Born at 363 ppm CO₂
🇳🇱☀️ In NL daalt de PV profiel factor met ~2,1% per GWp extra capaciteit.
Sinds 2018 van 100% naar <50% in 2025.

📉 Lineair: 0% bij 52 GWp
📉 Exponentieel: 22% bij 55 GWp

➡️ Meer zon = minder waarde per kWh. Tijd voor opslag & flexibiliteit! ⚡🔋

Prices of June and Juli 2025 in one graph:

- way less €0/MWh prices occured in Juli
August 2, 2025 at 10:52 AM
Ik analyseerde de PV weighted price van Juni vs Juli 2025 in NL:
- flink slechter weer
- veel meer bewolking hebben we gehad
- veel meer regenachtige dagen (zoals ook vandaag weer)

Zie hier de Day-Ahead resultaten, bron: NED.nl

er was flink minder PV productie, 15% minder GWh opgewekt in Juli

En voor Airco gebruik

Op basis van NED.nl CO2 emissie op uurbasis

En met @knmi.nl temp data van De Bilt

En EPEX prijs data van Entsoe

Wat is de gewogen gemiddelde uitstoot van het verbruik van een warmtepomp op jaarbasis? 2024

Antwoord:
241 gCO_2 / kWh elektrisch

Daar produceert de warmtepomp gemiddeld 4.6 kWh_thermisch voor

Dus per kWh_th is dit 52 gCO_2/kWh_th

en is daarmee meer dan 4x schoner
dan warmte uit een CV ketel

In een Plotly dashboard ziet dat er zo uit:

PV waarde per maand, sinds 1 jan 2022, t/m 20 juli 2025

1) PV productie in MWh/MWp per maand
2) PV waarde in €/MWp/mnd
3) gemiddelde waarde Day-Ahead versus PV gewogen DA waarde

Ik heb zelf de PV profiel gewogen waarde op Day-Ahead markt uitgerekend

dit voor de PV orientatie mix zoals die in NL aanwezig is, door data van NED.nl

gecombineerd met Day-Ahead prijs data van Entsoe

Indeed, good point: here is the updated graph

showing combined fossil fuel use (gasoline + diesel)

versus electricity use from electric vehicles

Global transport energy trends from 2010 to 2050:
• 🟧 Gasoline gradually declines
• ⬛ Diesel follows a similar downward path
• 🟨 Electric vehicle electricity use grows rapidly and overtakes both by 2050

This visualization highlights the energy transition in transport

How this software helps me code 👩‍💻

Using VS Code with Github Copilot and Gemini 2.0 Flash

my Github repository: github.com/MaykThewesse...

see my screen recording:
May 25, 2025 at 5:35 PM
🚗 Gasoline car: 100 input → 30 useful (30% efficiency)
🚛 Diesel car: 100 input → 40 useful (40% efficiency)
⚡ Electric vehicle: ~47 input → 40 useful (85% efficiency)

🔋 EVs use less than half the energy compared to fossil cars for the same motion

Best is to transform trucking industry to electric

they only account for ~3% of vehicles on the road

but consume 28% of fuel for transport (!)

due to high number of operating hours per truck

-> Electric-truck with a 600kWh battery saves a lot of fuel and saves on costs!

🔥 Conventional heating (boilers):
- needs> 100 units of input energy to deliver 91% of useful heat

⚡ Heat pumps (COP 3.5):
-> needs only 17.1 units of input energy to deliver the same 60 units of heat.

~5.8x less input energy for the same comfort

Massive efficiency gain switching to heat pumps

That is an interesting one

Would it be profitable or sensible do to so do you think?

if Electric vehicles replaced all gasoline vehicles ⛽️

Wind and solar could already displace global gasoline demand ☀️💨

How do Dutch electricity prices evolve?

Here the hourly prices from 2024

- Hourly average price
Big dip during day-time
High prices during breakfast and evening

- Histogram shows distrubtion and occurance

Aah oke dus dan ga je beter scoren als je zo rond 18-20u inprikt

Slim laden is gelukt!
- Ingeprikt op zaterdag
- Zondag middag heeft de auto geladen tijdens goedkope uren

PV on East delivers high value per kWh

When factoring the production timeseries with the hourly day-ahead market annual sum

See here value of PV based on 2024 NL EPEX electricity prices ⚡️

Oeh interessant!

Maar ik krijg €0,35/kWh incl btw?
