Photovoltaics are a great technology for certain applications, and, in fact, we invest in photovoltaic technologies. But they're not good substitutes for grid electricity.
Germany has a lot of solar power. In fact, in 2005, some 55 or 57 percent of worldwide installations were photovoltaics in Germany. That's 57 percent of all worldwide solar photovoltaics. Because of the high feed-in tariff, they have a way of allowing you to produce electricity and ship it into the grid at very high prices.
There's a big difference between needs and requirements for grid-based electricity versus those for distributed rural homes or remote locations, or even rooftop solar, where photovoltaics do OK. The more economical a technology is, the faster we'll see adoption.
If you want to invest in early-stage technologies, putting a timeframe on it does behold you to Silicon Valley economics. You've got a certain time period where you have to make the money. And you have to invest that money whether you find good companies or not.
Energy consumption has to be managed by an intelligent grid when it comes to highly populated areas. Smart-grid technologies allow for the integration of renewable energy into the grid as well as energy from distributed sources.
The electric grid powers the lives of all Americans - we need to invest in the research to ensure our constituents, companies, and defense installations have electricity when they need it most.
Technology is technology. Technology doesn't have a, it is not good or bad. Technologies are tools.
Any good teacher should become acquainted with relevant technologies. But the technologies should not dictate an education goal. Rather, the teacher (or parent or student or policy maker) should ask: can technology help to achieve this goal, and which technologies are most likely to be helpful?
When people come and invest in India, they invest on a certain premise, and the fact that the very premise can change worries them a lot.
If it's in people's interest to invest in renewables and invest in clean technologies, I'm convinced it will happen.
People always think of technology as something having silicon in it. But a pencil is technology. Any language is technology. Technology is a tool we use to accomplish a particular task and when one talks about appropriate technology in developing countries, appropriate may mean anything from fire to solar electricity.
If we can speed up the deployment of clean energy technologies in developing countries with investments from the Green Climate Fund, hundreds of millions of people will be able to access electricity for the first time - with all the education, health, communication and entrepreneurial opportunities electricity enables.
By lowering the barrier to create new digital currency applications, we'll see an explosion in the number of ideas tried. We'll invest in, partner with, or build a number of new applications in this space, including replacements for many of the services people use in finance 1.0.
A reliable electric grid is absolutely necessary to provide drinking water. You have to have the electricity.
Electricity is an example of a general purpose technology, like the steam engine before it. General purpose technologies drive most economic growth, because they unleash cascades of complementary innovations, like lightbulbs and, yes, factory redesign.
Don't be governed by the grid, govern the grid. A grid is like a lion cage - if the trainer stays too long it gets eaten up. You have to know when to leave the cage - you have to know when to leave the grid.
Technology, and applications of this technology, will continue to improve and evolve, providing unprecedented, global access to information, individuals, training, and opportunities.
