Read the following scenario and answer the questions. A local school aims to reduce its carbon footprint. In $2023$, the school produced $1500$ kg of waste. In $2024$, thanks to a new recycling program, they reduced this by $20\%$ and saved $400$ kWh of electricity. 1. Calculate the total weight of waste in $2024$ in kg. 2. Write a short paragraph (three sentences) in English explaining why reducing electricity consumption (measured in kWh) is crucial for the environment. Use at least one comparative form (e.g., cleaner, more efficient) and the modal verb 'should'.
