The renewable industry claims technical innovations will improve solar and wind - but in reality nothing can change the lower power density of sunlight and wind.

Nuclear is the largest source of clean, carbon-free power in rich nations, and the science shows it is the safest way to make reliable electricity.

Most people think of solar and wind as new energy sources. In fact, they are two of our oldest.

The flip side of renewables' low energy density is their low return on energy invested.

Solar makes electricity expensive for two inherently physical reasons. Sunlight is dilute, requiring 10 to 15 times as much materials and mining, and up to 5,000 times more land, than non-renewables. And sunlight is unreliable, which reduces the value of solar as it becomes a larger part of energy supplies.

Voters must feel that that the burden of new housing is being shared equally and not falling disproportionately on any one group.

Neither solar nor wind are actually substitutes for coal or natural gas or oil.

If you want to save the natural environment, you just use nuclear. You grow more food on less land, and people live in cities. It's not rocket science.

In truth, humankind has never been at risk of running out of energy.

Cold white wine is so good with fatty, fried food.

At 17, I lived in Nicaragua to show solidarity with the Sandinista socialist revolution. At 23 I raised money for Guatemalan women's cooperatives. In my early 20s I lived in the semi-Amazon doing research with small farmers fighting land invasions. At 26 I helped expose poor conditions at Nike factories in Asia.

Climate change is happening. It's just not the end of the world. It's not even our most serious environmental problem.

Climate change is an issue I care passionately about and have dedicated a significant portion of my life to addressing.

Allowing for suburbanization of California's ranches and farmlands would still allow for strong protections of California's truly natural areas like Yosemite, the redwoods, and oak woodlands and green spaces near cities.

The Amazon uses as much oxygen as it produces.

Journalists and activists alike have an obligation to describe environmental problems honestly and accurately, even if they fear doing so will reduce their news value or salience with the public.

The producers of 'Chernobyl' should tell the truth: the accident demonstrates the relative safety, not danger, of nuclear power.

The underlying problem with solar and wind is that they are too unreliable and energy-dilute.

Nuclear is the only energy source that has proven capable of fully replacing fossil fuels at low-cost in wealthy nations. While hydro-electric dams can sometimes play that role, they are limited to nations with powerful rivers, many of which have already been dammed.

All renewables thus require a material throughput - from mining to processing to installing to disposing of the materials later as waste - that is orders of magnitude larger than for non-renewable energy sources.
