Garrett Durning of the Texas Environmental Defense League has spent the last three months campaigning tirelessly for the installation of solar-powered electric chairs in state prisons. 'Texas wastes more than 500,000 watts of electricity on every criminal it executes,' Durning told reporters Monday. 'We live in the 21st century, and it's high time we acted like it. Let's stop depleting our non-renewable fossil fuels. Solar power is a more energy-efficient way to execute the condemned.' Durning added that wrist and ankle restraints should be made of hemp rather than leather, the use of which is cruel.
