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.

We are going to have peace even if we have to fight for it.

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.

By the time we see that climate change is really bad, your ability to fix it is extremely limited… The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed. That means that even when you turn virtuous, things are actually going to get worse for quite a while.

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

The most interesting biofuel efforts avoid using land that’s expensive and has high opportunity costs. They do this by getting onto other types of land, or taking advantage of byproducts that aren’t used in the food chain today, or by intercropping.

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.

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.

In the case of the environment, there’s no one to bail it out.

The crimes against Palestinians in the Occupied Territories and elsewhere, particularly Lebanon, are so shocking that the only emotionally valid reaction is rage and a call for extreme actions. But that does not help the victims. And, in fact, it’s likely to harm them.

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

The world is too violent right now.

You’re never going to get the amount of CO2 emitted to go down unless you deal with the one magic metric, which is CO2 per kilowatt-hour.

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.

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.

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 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.

At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?

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.

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.

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.

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.

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

We should no longer measure our wealth and success in the graph that shows economic growth, but in the curve that shows the emissions of greenhouse gases.

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.

It’s not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it’s a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.

Can you imagine what a different world we will live in when businesses do what’s right for the communities and the environment in everything they do?

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.

A company shouldn’t get addicted to being shiny, because shiny doesn’t last.

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’m glad to see that BMW is bringing an electric car to market. That’s cool.

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.

Let us move from the era of confrontation to the era of negotiation.

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.

What is a farm but a mute gospel?

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

The universal utilization of water power and its long-distance transmission will supply every household with cheap power and will dispense with the necessity of burning fuel. The struggle for existence being lessened, there should be development along ideal rather than material lines.

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

Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.

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 shift to a cleaner energy economy wont happen overnight, and it will require tough choices along the way. But the debate is settled. Climate change is a fact.

If you want peace, you don’t talk to your friends. You talk to your enemies.

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.

Obviously Tesla is about helping solve the consumption of energy in a sustainable manner, but you need the production of energy in a sustainable manner.

I do not believe there is a problem in this country or the world today which could not be settled if approached through the teaching of the Sermon on the Mount.

If you want to be a voice for peace in the world, begin by making peace a permanent condition of your own life.

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

The environment is everything that isn’t me.

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 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.

We should remember that there are nations which meet more than 30 to 60% of their power requirements through the nuclear power system.

The world, we are told, was made especially for man – a presumption not supported by all the facts. A numerous class of men are painfully astonished whenever they find anything, living or dead, in all God’s universe, which they cannot eat or render in some way what they call useful to themselves.

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

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

Disarmament, with mutual honor and confidence, is a continuing imperative.

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

A business that makes nothing but money is a poor business.

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.

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.

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.

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.
