Businesses are asking how much attention they should be paying to blockchain now and what the opportunities are for this crypto-technology in the future. In this podcast episode, Dan Wellers, Global Lead for Digital Futures for SAP, ventures into the coming possibilities of blockchain for renewables and the entire e…

Tell Environmental Protection Agency (EPA) Administrator Scott Pruitt that you are outraged that he is putting fossil fuel industry profits ahead of the health and safety of the public by repealing the Clean Power Plan.

Solar dish/engine systems always point straight at the sun and concentrate the solar energy at the focal point of the dish. A solar dish’s concentration ratio is much higher than linear concentrating systems, and it has a working fluid temperature higher than 1,380°F. The power-generating equipment used with a solar dish can be mounted at the focal point of the dish, making it well suited for remote locations, or the energy may be collected from a number of installations and converted into electricity at a central point.

The International Organization for Standardization has established several standards relating to solar energy equipment. For example, ISO 9050 relates to glass in building while ISO 10217 relates to the materials used in solar water heaters.

Utility investors are accustomed to large, long-term, reliable investments with a 30-year cost recovery — fossil fuel plants, basically. The cost of those investments, along with investments in grid maintenance and reliability, are spread by utilities across all ratepayers in a service area. What happens if a bunch of those ratepayers start reducing their demand or opting out of the grid entirely? Well, the same investments must now be spread over a smaller group of ratepayers. In other words: higher rates for those who haven’t switched to solar.

At the end of 2016 there were 1.76 GW total installed capacity of solar thermal power across the United States,[2] the contribution to the US electric grid since 2004 can be seen in the table at the end of this section.

Solar cooking uses the Sun as the source of energy instead of standard cooking fuels such as charcoal, coal or gas. Solar cookers are an inexpensive and environmentally sound alternative to traditional ovens. They are becoming widely used in areas of the developing world where deforestation is an issue, financial resources to purchase fuel are limited, and where open flames would pose a serious risk to people and the environment. Solar cookers are covered with a glass plate. They achieve a higher temperature by using mirrors to focus the rays of the sun.
