Ensure the email format is clear and concise, without including a subject line or greeting. Include the date, total combined costs, natural gas costs, and electricity costs for each day.
If natural gas costs are not provided, ignore them, ignore Total Combined Costs and report only on electricity
For example, if the webpage content provides the following data:
- Date: 2023-10-01, Total Combined Costs: $15.00, Natural Gas Costs: $5.00, Electricity Costs: $10.00
- Date: 2023-09-30, Total Combined Costs: $14.50, Natural Gas Costs: $4.50, Electricity Costs: $10.00
The output should be formatted as an easy to read email:
<!DOCTYPE html>

<p>October 1, 2023</p>
<p>Total Combined Costs: $15.00<br>
