All the waste in a year from a nuclear power plant can be stored under a desk.

You need to live in a dome initially, but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on… So it’s a fixer-upper of a planet.

I think it is a good thing to buy less and choose well – it’s good for the environment and to be fair it’s also good for me because my clothes are quite expensive.

The future is green energy, sustainability, renewable energy.

An important priority for me is a business must get their own house in order. Be or become an agent of positive change in your own enterprise and adopt responsible practices to eliminate the risks that often lie at the root of inequality and poverty.

As soon as a redwood is cut down or burned, it sends up a crowd of eager, hopeful shoots, which, if allowed to grow, would in a few decades attain a height of a hundred feet, and the strongest of them would finally become giants as great as the original tree.

I just think people should invest in the world. Don’t invest in fashion, but invest in the world.

Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill.

Enthusiasm is the yeast that makes your hopes shine to the stars. Enthusiasm is the sparkle in your eyes, the swing in your gait. The grip of your hand, the irresistible surge of will and energy to execute your ideas.

We could have saved the Earth but we were too damned cheap.

Energy innovation is not a nationalistic game.

The redwood is the glory of the Coast Range. It extends along the western slope, in a nearly continuous belt about ten miles wide, from beyond the Oregon boundary to the south of Santa Cruz, a distance of nearly four hundred miles, and in massive, sustained grandeur and closeness of growth surpasses all the other timber woods of the world.

I feel a distaste for hunting, first because of a kind of Buddhist respect for the unity and sacredness of all life, and also because the pursuit of a hare or chamois strikes me as a kind of ‚escape of energy,‘ that is, the expenditure of our effort in an illusory end, one devoid of profit.

Treatment without prevention is simply unsustainable.

In 80% of the world, energy will be bought where it is economic. You have to help the rest of the world get energy at a reasonable price.

First, I want to pay tribute to Diana myself. She was an exceptional and gifted human being. In good times and bad, she never lost her capacity to smile and laugh, nor to inspire others with her warmth and kindness. I admired and respected her – for her energy and commitment to others, and especially for her devotion to her two boys.

People from all over the world come to London wanting to make their own mark on it, and they add to the energy and vitality of the capital. It’s got a bit busier since the ’60s, but the more the merrier!

If you think in terms of a year, plant a seed; if in terms of ten years, plant trees; if in terms of 100 years, teach the people.

Any fool can destroy trees. They cannot run away; and if they could, they would still be destroyed – chased and hunted down as long as fun or a dollar could be got out of their bark hides, branching horns, or magnificent bole backbones.

You can’t generalise about an entire country, but I like the energy of British men.

Thanks to my mother, not a single cardboard box has found its way back into society. We receive gifts in boxes from stores that went out of business twenty years ago.

The main thing that’s missing in energy is an incentive to create things that are zero-CO2-emitting and that have the right scale and reliability characteristics.

There is nothing wrong with America that faith, love of freedom, intelligence, and energy of her citizens cannot cure.

Avoiding climate breakdown will require cathedral thinking. We must lay the foundation while we may not know exactly how to build the ceiling.

When I was a little girl you used to learn to sew all the holes in things, darning socks, but nobody mends things anymore.

Taking bold action on climate change simply makes good business sense. It’s also the right thing to do for people and the planet. Setting a net-zero GHG emissions target by 2050 will drive innovation, grow jobs, build prosperity, and secure a better world for what will soon be 9 billion people.

In just a few hundred years, we will have to cover the entire surface of the Earth in solar cells if we want to continue to grow our energy usage.

The threat to the planet is us. It’s actually not a threat to the planet – it’s a threat to us.

The effects of climate change are real and must be acted on.

What is the use of a house if you haven’t got a tolerable planet to put it on?

I resigned from the Marine Corps and flying in 1974, even though I loved them both. I quit because I no longer wanted to fight for peace. Instead, I believe we can build a more sustainable peace by working for prosperity.

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.

Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it’s about 20 tons. For people in poor countries, it’s less than one ton. It’s an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero.

Nothing is being done to stop the climate and ecological emergency from happening and to secure the future wellbeing for future generations.

All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction.

It is only through labor and painful effort, by grim energy and resolute courage, that we move on to better things.

In most mills, only the best portions of the best trees are used, while the ruins are left on the ground to feed great fires which kill much of what is left of the less desirable timber, together with the seedlings on which the permanence of the forest depends.

I remember when I was younger, and in school, our teachers showed us films of plastic in the ocean, starving polar bears and so on. I cried through all the movies. My classmates were concerned when they watched the film, but when it stopped, they started thinking about other things. I couldn’t do that. Those pictures were stuck in my head.

To shake your rump is to be environmentally aware.

The environment is everything that isn’t me.

I don’t know if I could do this with the same energy, and in the same way – all the costume changes and glitter and hair and makeup – all the time. When I’m in my 50s, I kind of think I’ll want to be in a garden.

Economists treat economics as if it is a pure science divorced from the facts of life. The result of this false accountancy is a willful confusion under cover of which industry wreaks its havoc scot-free and ignores the environmental cost.

I was born in London in England in 1934. I went through, as a child, the horrors of World War II, through a time when food was rationed and we learned to be very careful, and we never had more to eat than what we needed to eat. There was no waste. Everything was used.

We need to keep making our streets safer and our criminal justice system fairer – our homeland more secure, our world more peaceful and sustainable for the next generation.

It is wonderful how much time good people spend fighting the devil. If they would only expend the same amount of energy loving their fellow men, the devil would die in his own tracks of ennui.

I know a man who doesn’t pay to have his trash taken out. How does he get rid of his trash? He gift wraps it, and puts in into an unlocked car.

If future generations are to remember us more with gratitude than sorrow, we must achieve more than just the miracles of technology. We must also leave them a glimpse of the world as it was created, not just as it looked when we got through with it.

I have lived in countries that were coming out of conflict: Ireland, South Africa, the Czech republic. People there are overflowing with energy.

Nobody realizes that some people expend tremendous energy merely to be normal.

I always knew that St. Jude was an amazing organization but meeting the kids and seeing how the hospital works first hand was truly beautiful. It doesn’t feel like a regular hospital all dreary and sad. It’s a colorful, beautiful, comfortable, fun place to live and the energy is wonderful.

We must get rid of fossil fuels by developing injection systems for automobiles, which can run on bio-fuel.

I have been on the road and visited numerous places and met people from all over the globe. I can say that it looks nearly the same everywhere I have been: The climate crisis is ignored by people in charge, despite the science being crystal clear.

I am always trying to find fabrics that are more friendly to the environment – working with Virgin Atlantic, they managed to research into this and find more eco fabrics.

There is a sufficiency in the world for man’s need but not for man’s greed.

I think there are more politicians in favor of electric cars than against. There are still some that are against, and I think the reasoning for that varies depending on the person, but in some cases, they just don’t believe in climate change – they think oil will last forever.

I have a private plane. But I fly commercial when I go to environmental conferences.

This is absolutely bizarre that we continue to subsidize highways beyond the gasoline tax, airlines, and we don’t subsidize, we don’t want to subsidize a national rail system that has environmental impact.

If you don’t have sustainable energy, you have unsustainable energy. The fundamental value of a company like Tesla is the degree to which it accelerates the advent of sustainable energy faster than it would otherwise occur.

I’ve actually made a prediction that within 30 years a majority of new cars made in the United States will be electric. And I don’t mean hybrid, I mean fully electric.

While some doubted that connecting the world was actually important, we were building. While others doubted that this would be sustainable, you were forming lasting connections. We just cared more about connecting the world than anyone else. And we still do today.

Ideas excite me, and as soon as I get excited, the adrenaline gets going and the next thing I know I’m borrowing energy from the ideas themselves.
