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.

I think California has the best energy.

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

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.

Today we say that the law of relativity is supposed to be true at all energies, but someday somebody may come along and say how stupid we were.

You should be attacking the carbon emissions, period, and whether it’s cap-and-trade or carbon tax or whatever, that’s the realm in which we should be playing.

People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.

The environment is everything that isn’t me.

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.

A utility can handle up to 20% of production from solar and that helps the grid because it produces electricity when needed. Solar power peaks in the middle of the day and that’s also when air conditioning is running and businesses are operating, so power production matches usage.

We can’t drive our SUVs and eat as much as we want and keep our homes on 72 degrees at all times… and then just expect that other countries are going to say OK. That’s not leadership. That’s not going to happen.

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.

Let us not be too particular; it is better to have old secondhand diamonds than none at all.

Computers are still technology because we are still wrestling with it: it’s still being invented; we’re still trying to work out how it works. There’s a world of game interaction to come that you or I wouldn’t recognise. It’s time for the machines to disappear. The computer’s got to disappear into all of the things we use.

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.

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

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

In the future, you won’t buy artists‘ works; you’ll buy software that makes original pieces of ‚their‘ works, or that recreates their way of looking at things. You could buy a Shostakovich box, or you could buy a Brahms box. You might want some Shostakovich slow-movement-like music to be generated. So then you use that box.

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.

What is a farm but a mute gospel?

Without electricity, the air would rot.

When we build, let us think that we build for ever.

Over time I think we will probably see a closer merger of biological intelligence and digital intelligence.

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 most compelling reason for most people to buy a computer for the home will be to link it to a nationwide communications network. We’re just in the beginning stages of what will be a truly remarkable breakthrough for most people – as remarkable as the telephone.

More businesses should be following Apple’s stance in encouraging more investment in sustainability.

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

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.

Treatment without prevention is simply unsustainable.

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

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

We’ve gotta reinvest in space travel. We should’ve never left the moon.

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.

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.

When the well is dry, they know the worth of water.

In the absence of sound oversight, responsible businesses are forced to compete against unscrupulous and underhanded businesses, who are unencumbered by any restrictions on activities that might harm the environment, or take advantage of middle-class families, or threaten to bring down the entire financial system.

Today, we’re very dependent on cheap energy. We just take it for granted – all the things you have in the house, the way industry works.

I do think that we’re gonna move towards this world where eventually you’ll be able to capture a whole experience that you’re in and be able to send that to someone.

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

We just think that there are all these different ways that people want to share, and that compressing them all into a single blue app is not the right format of the future.

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

I really do encourage other manufacturers to bring electric cars to market. It’s a good thing, and they need to bring it to market and keep iterating and improving and make better and better electric cars, and that’s what going to result in humanity achieving a sustainable transport future. I wish it was growing faster than it is.

We shouldn’t be saying ‚Save the planet‘; we should be saying: ‚Save viable conditions in which people can live.‘ That’s what we’re dealing with here.

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

Most emissions aren’t caused by individuals, they’re caused by corporations and states.

The situation the Earth is in today has been created by unmindful production and unmindful consumption. We consume to forget our worries and our anxieties. Tranquilising ourselves with over-consumption is not the way.

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

With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code.

If humanity doesn’t land on Mars in my lifetime, I would be very disappointed.

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

To shake your rump is to be environmentally aware.

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.

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.

Gardening is not a rational act.

This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.

Stationary storage will be as big as the car business long term. The growth rate will probably be several times what it is for the car business.

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.

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

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.

As Irving Good realised in 1965, machines with superhuman intelligence could repeatedly improve their design even further, triggering what Vernor Vinge called a ‚singularity.‘

There aren’t many things that are universally cool, and it’s cool not to litter. I’d never do it.
