What does GreenTime do?
GreenTime provides real-time carbon intensity data for the Los Angeles power grid, helping you make informed decisions about when to use high-energy appliances. By understanding when the grid is running on cleaner energy sources, you can shift activities like EV charging, laundry, or dishwashing to lower-emission times.
Key Features:
• Live Grid Data - Real-time carbon intensity measurements from LADWP via GridStatus.io EIA-930 reporting, updated throughout the day
• 24-Hour Chart - Visual graph showing carbon intensity levels for every hour of the current day, color-coded by emission levels (green for clean, yellow for moderate, red for high)
• Current Status - See the exact carbon intensity right now with real-time updates and color-coded status indicators
• Personalized Energy Schedule - Schedule that GreenTime generates based on information that user inputs and current grid status
• Green Points - Track your sustainability by inputting the times of day you used energy and earn badges!
• Seasonal Patterns - View historical carbon intensity patterns by season (Spring, Summer, Fall, Winter) to understand how grid emissions vary throughout the year
• Smart Notifications - Optional push alerts notify you when optimal low-emission time windows begin, helping you remember to start high-energy tasks
• Carbon Calculator - Calculate the carbon intensity of different appliances at different times of day and compare the amount of carbon that can be saved!
• Educational Content - Learn about carbon intensity, how the LA grid works, and why renewable energy availability changes throughout the day
• Daily Streak - Keep track of the amount of days use use GreenTime in a row. This is how you know you are making an impact!
How It Works:
The app displays carbon intensity measured in pounds of CO₂ per megawatt-hour (lbs CO₂/MWh). Lower numbers mean cleaner energy from sources like solar and wind. Higher numbers indicate the grid is relying more on fossil fuels.
Carbon intensity fluctuates based on electricity demand, weather patterns, and renewable energy availability. Solar power typically makes midday the cleanest time, while evening hours when solar fades often have higher emissions.
Data Source:
All carbon intensity data comes from GridStatus.io, which aggregates official LADWP EIA-930 grid reporting. The app uses actual historical patterns to provide accurate daily estimates that reflect real grid behavior.
Who Should Use GreenTime:
• EV owners wanting to charge during cleaner grid times
• Environmentally conscious LA residents seeking to reduce their carbon footprint
• Anyone interested in understanding LA's energy landscape
• People looking to optimize high-energy tasks for lower emissions
