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

We will have to leave this planet, and we’re going to leave it, and it’s going to make this planet better.

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.

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

We need enlightenment, not just individually but collectively, to save the planet. We need to awaken ourselves. We need to practice mindfulness if we want to have a future, if we want to save ourselves and the planet.

I have seen firsthand that agricultural science has enormous potential to increase the yields of small farmers and lift them out of hunger and poverty.

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.

We have to rethink our whole energy approach, which is hard to do because we’re so dependent on oil, not just for fuel but also plastic. If plastic vanished, there would be total chaos. We have to think quite carefully about using oil and its derivatives, because it’s not going to be around forever.

A diplomatic solution that puts significant and verifiable constraints on Iran’s nuclear program represents the best and most sustainable chance to ensure that America, Israel, the entire Middle East will never be menaced by a nuclear-armed Iran.

To make a prairie it takes a clover and one bee, One clover, and a bee, And revery. The revery alone will do, If bees are few.

Evolution can go to hell as far as I am concerned. What a mistake we are. We have mortally wounded this sweet life-supporting planet – the only one in the whole Milky Way – with a century of transportation whoopee.

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

Without electricity, the air would rot.

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.

Here at this site, Solyndra expects to make enough solar panels each year to generate 500 megawatts of electricity. And over the lifetime of this expanded facility, that could be like replacing as many as eight coal-fired power plants.

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.

To shake your rump is to be environmentally aware.

I mean, people aren’t continuing like this and not doing anything because they are evil, or because they don’t want to. We aren’t destroying the biosphere because we are selfish. We are doing it simply because we are unaware.

I’m not saying that people should stop flying. I’m just saying it needs to be easier to be climate neutral.

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.

The reason we should do a carbon tax is because it’s the right thing to do. It’s economics 101, elementary stuff.

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.

We can’t just continue living as if there was no tomorrow, because there is a tomorrow.

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.

It’s obviously tricky to convert cellulose to a useful biofuel. I think actually the most efficient way to use cellulose is to burn it in a co-generation power plant. That will yield the most energy and that is something you can do today.

There must be a reason why some people can afford to live well. They must have worked for it. I only feel angry when I see waste. When I see people throwing away things that we could use.

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.

The environmentalists say capitalism is killing our oceans, air, land, and forests. Capitalists argue that they provide food, fuel, and building materials for a growing world.

Sweden is not a green paradise, it has one of the biggest carbon footprints.

If burning fossil fuels was so bad that it threatened our very existence, how could we just continue like before? Why were there no restrictions? Why wasn’t it made illegal? To me, that did not add up.

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.

Gain may be temporary and uncertain; but ever while you live, expense is constant and certain: and it is easier to build two chimneys than to keep one in fuel.

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

I have a company, and I’ve got to think about that. I’m trying to do my best there, and that’s a much harder task. We recycle as much as possible, and we conserve. But I’ve always been one to save everything – I even walk up stairs on the very inside or the very outside to not wear out the tread.

By stopping flying, you don’t only reduce your own carbon footprint but also that sends a signal to other people around you that the climate crisis is a real thing and that helps push a political movement.

If anyone has a vested interest in space solar power, it would have to be me.

I’m frugal. I’m not a very acquisitive woman. I never waste food. If you prepare your own food, you engage with the world, it tastes alive. It tastes good.

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.

If a man walks in the woods for love of them half of each day, he is in danger of being regarded as a loafer. But if he spends his days as a speculator, shearing off those woods and making the earth bald before her time, he is deemed an industrious and enterprising citizen.

I’ve been very passionate about renewable energy for many years, particularly solar energy and its capacity to bring abundant clean, sustainable energy to millions around the globe.

The main message we want to get out there is that climate change is caused by the rotten economic system.

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.

Well, capitalism is a big problem, because with capitalism you’re just going to keep buying and selling things until there’s nothing else to buy and sell, which means gobbling up the planet.

In energy, you have to plan and do research way in advance, sometimes decades in advance to get a new system that’s safer, doesn’t require us to go around the world to get all our oil.

I did this book ‚Harvest for Hope,‘ and I learned so much about food. And one thing I learned is that we have the guts not of a carnivore, but of an herbivore. Herbivore guts are very long because they have to get the last bit of nutrition out of leaves and things.

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.

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

Treatment without prevention is simply unsustainable.

Gardening is not a rational act.

We’ve gotta become the Martians. I’m a Martian – I tell you to become Martians. And we’ve gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

It is good to realize that if love and peace can prevail on earth, and if we can teach our children to honor nature’s gifts, the joys and beauties of the outdoors will be here forever.

Two out of every five people on Earth today owe their lives to the higher crop outputs that fertilizer has made possible.

The nuclear approach I’m involved in is called a traveling-wave reactor, which uses waste uranium for fuel. There’s a lot of things that have to go right for that dream to come true – many decades of building demo plants, proving the economics are right. But if it does, you could have cheaper energy with no CO2 emissions.

I threw my cup away when I saw a child drinking from his hands at the trough.

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.

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.

There are thousands of ways to take action. For example, plant trees, pick up litter, join an organisation or movement that makes a difference and especially try to influence adults and put pressure on people in power.

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 really wonder what gives us the right to wreck this poor planet of ours.

Many people, especially in the U.S., see countries like Sweden or Norway or Finland as role models – we have such a clean energy sector, and so on. That may be true, but we are not role models.
