Texas Braces for Energy Challenges Amid Heat Wave and Low Wind.

Texas is experiencing a heat wave that could break more than 75 heat records this week, raising the potential for record energy usage and pushing the Texas energy grid to its brink. The extreme temperatures across the state are a direct result of the heat wave, with air conditioners running at full blast. ERCOT has issued a "weather watch" through June 21, but assures residents that the supply should be efficient, avoiding blackouts. Climate Central's Climate Shift Index shows how climate change impacts day-to-day weather in a specific area, with several Texas cities experiencing a significant increase in daily temperatures in recent years.
