New tool estimates solar and wind power production based on weather forecasts

Happy Monday and welcome to another edition of the Beyond The Forecast newsletter! We’ve been talking a lot about sustainable sources of energy lately, due to Earth Day last week.

A new tool developed by Climate Central can show us how much solar and wind energy is being produced in each county in our corner of the Commonwealth!

It’s called WeatherPower and uses National Weather Service forecasts, along with information about existing renewable energy sources, to predict how much energy will be generated on a given day.

Here’s an example of how much solar energy was produced in Virginia today. You can customize the graphics to show yesterday’s data and forecasts for up to three days in advance.

The numbers make sense, due to the amount of sunshine we saw today and how much is in the forecast tomorrow. More clouds yesterday kept the production down some.

Virginia is not a hotspot for wind energy just yet, although that could change if the Botetourt wind farm project is able to fight through its legal battles.

We can use another state that’s big on wind energy, Texas, to show you WeatherPower’s metrics.

Lots of turbines means lots of electricity generated by the wind in the Lone Star State.

A new feature from WeatherPower? The addition of the Spanish language to their graphics!

Below, we have the three-day solar energy forecast for Roanoke in Spanish, broken down into car miles, trees planted and smartphones charged.

I think the coolest thing about this tool is the ability to break down the energy produced county-by-county!

Roanoke County is projected to produce enough solar energy to charge 1.4 million smartphones tomorrow! The solar energy production looks good later in the week, too.

Feel free to fiddle around with this tool yourself! It will be interesting to see how the numbers change in the coming years as solar and wind energy becomes more prominent in our society.

Switching gears to your forecast, today was a top 10 weather day in Southwest and Central Virginia! If you liked today’s warm-up, you’ll love what we’re expecting in the coming days. Meteorologist Chris Michaels breaks it down in our daily forecast article.
