Quotes About Energy

It appears that the universe may not only be filled with dark matter, but with dark energy.

With their radio telescopes they can capture wisps of radiation so preposterously faint that the total amount of energy collected from outside the solar system by all of them together since collecting began (in 1951) is 'less than the energy of a single snowflake striking the ground'2, in the words of Carl Sagan. In

Mitochondria manipulate oxygen in a way that liberates energy from foodstuffs. Without this niftily facilitating trick, life on Earth today would be nothing more than a sludge of simple microbes.

There is energy of all sorts flowing through our world; it is not hard to imagine new ways in which that energy can do the work of humanity, new ways to align our needs and the planet's behaviours.

Electric jugs for all.

The author says the earliest Australian aborigines devoted extraordinary amounts of energy to enterprises no one now can understand.

But I hope you'll spend more time and energy supporting whatever you're in favor of than opposing whatever you're against.

Remember that we need to find solutions for all five activities that emissions come from: making things, plugging in, growing things, getting around, and keeping cool and warm.

times with follow-up questions. Eventually it sank in. The world needs to provide more energy so the poorest can thrive, but we need to provide that energy without releasing any more greenhouse gases. Now the problem seemed even harder. It wasn't enough to deliver cheap, reliable energy for the poor. It also had to be clean.

Solar cells, for example, got almost 10 times cheaper between 2010 and 2020, and the price of a full solar system went down by 11 percent in 2019 alone.

the problem of overgeneration in the summer and undergeneration in the winter.

Just think about how many landowners, utility companies, and local and state governments you'd need to bring together to build power lines that could move solar energy from the Southwest all the way to customers in New England. Merely picking the routes and establishing rights-of-way would be a massive undertaking; people tend to object when you want to run a big power line through the local park.

In the coming years, as electricity becomes an even bigger part of our overall energy diet, we'll need models like these for grids around the world. They'll help us answer questions like: Which mix of clean energy sources will be the most efficient in a given place? Where should transmission lines go? Which regulations stand in the way, and what incentives do we need to create? I hope to see a lot more projects like this one.

divested all my direct holdings in oil and gas companies, as did the trust that manages the Gates Foundation's endowment. (I hadn't had money in coal companies in several years.)

that a lot? Over the past decade, we've added an average of 22 gigawatts a year. Now we need to install more than three times that much each year, and keep up the pace for the next three decades.

The Green Premiums answer these questions, measuring the cost of getting to zero, sector by sector, and highlighting where we need to innovate

I didn't think it was fair for anyone to tell Indians that their children couldn't have lights to study by, or that thousands of Indians should die in heat waves because installing air conditioners is bad for the environment. The only solution I could imagine was to make clean energy so cheap that every country would choose it over fossil fuels.

The reason the world emits so much greenhouse gas is that—as long as you ignore the long-term damage they do—our current energy technologies are by and large the cheapest ones available. So moving our immense energy economy from "dirty," carbon-emitting technologies to ones with zero emissions will cost something.

Getting all the world's electricity from clean sources won't be easy. Today, fossil fuels account for two-thirds of all electricity generated worldwide. (bp Statistical Review of World Energy 2020)

The world needs to provide more energy so the poorest can thrive, but we need to provide that energy without releasing any more greenhouse gases.

At Breakthrough Energy, we fund only technologies that could remove at least 500 million tons a year if they're successful and fully implemented. That's roughly 1 percent of global emissions. Technologies that will never exceed 1 percent shouldn't compete for the limited resources we have for getting to zero. There may be other good reasons to pursue them, but significantly reducing emissions won't be one of them.

fission, carbon capture and sequestration, offshore wind, cellulosic ethanol (a type of advanced biofuel), and meat alternatives.

It was one thing to divest from companies to fight apartheid, a political institution that would (and did) respond to economic pressure. It's another thing to transform the world's energy system—an industry worth roughly $5 trillion a year and the basis for the modern economy—just by selling the stocks of fossil-fuel companies.
