Final answer:
Lowering the thermostat temperature can reduce energy consumption and save money. Adding cream before letting coffee sit for 5 minutes will give hotter coffee. Using more efficient devices can help save energy and money.
Step-by-step explanation:
When it comes to heating and saving money, it's important to consider the trade-off between the temperature and energy usage. Lowering the thermostat temperature can significantly reduce energy consumption and save money in the long run. However, it's also crucial to maintain a temperature that will prevent damage to the house, such as freezing pipes.
As for the coffee question, adding cream before letting the coffee sit for 5 minutes will give you hotter coffee. This is because the cream and coffee reach thermal equilibrium quickly, so adding cream before waiting allows more time for the coffee to cool down.
Overall, reducing high-power device usage and using more efficient devices, such as compact fluorescent light bulbs, can help save energy and money.
