Renewables Give Us More Power Than Nuclear

Renewables Give Us More Power Than Nuclear

Discusses the recent news that renewable energy (including hydro as well) now supplies more electricity to the US grid than does nuclear power. The post then goes on to list some large solar and wind projects in advanced stages of the development pipeline as a reason for being optimistic that the solar and wind side of the renewables is rapidly growing in scale.

Natural Gas Complements Wind & Solar — Or Does It?

Natural Gas Complements Wind & Solar — Or Does It?

This post looks at the message promoted by the gas industry that natural gas is the necessary complement to renewables such as solar and wind, because the latter are variable and thus need a backup power source that can quickly be brought on line. There are other and perhaps even better ways of addressing variability that also need looking at.

Ultra High Voltage (UHV) Transmission is the Renewable Energy Interstate

Ultra High Voltage (UHV) Transmission is the Renewable Energy Interstate

While other parts of the world are busy actually building national Ultra High Voltage (UHV) transmission infrastructure the US continues to do noting more substantial than litigate. A UHV super grid would be able to move renewable energy from where it is abundant to where people live and work, and do so at an economic cost. This kind of national electric energy infrastructure would enable solar, wind, hydro and geothermal generated electric power to reach market. It is a critical piece of the kind of future energy infrastructure we will need in order to continue to prosper. John goes into a lot of detail and provides numerous links to examples and more in depth reading on this very important subject.

Can Electric Vehicles Take Off? A Roadmap to Find the Answer

Can Electric Vehicles Take Off? A Roadmap to Find the Answer

Electric cars are finally coming to market in the U.S., but what is the future potential for this much-touted technology? A good way to find out would be to launch demonstration projects in selected U.S. cities to determine if, given incentives and the proper infrastructure, the public will truly embrace plug-in vehicles.

Does Concentrated Solar Power Have the Answer to Intermittency Concerns?

Does Concentrated Solar Power Have the Answer to Intermittency Concerns?

In this post John outlines two developments in the thermosolar concentrated solar power (CSP) arena that are enabling CSP to fulfill the role of baseload suppliers. Molten salt energy storage is naturally suited for CSP facilities and is quite efficient as an energy store — both in terms of low loss and in terms of capital expenditures (compared with batteries for example). By storing power in this way CSP plants can continue delivering power even after the sun has gone down. In addition by pairing CSP with stand-by combined-cycle natural gas generators greater overall reliability can be achieved.

Green Energy’s Big Challenge: The Daunting Task of Scaling Up

Green Energy’s Big Challenge: The Daunting Task of Scaling Up

To shift the global economy from fossil fuels to renewable energy will require the construction of wind, solar, nuclear, and other installations on a vast scale, significantly altering the face of the planet. Can these new forms of energy approach the scale needed to meet the world’s energy demands?

Rising Hopes that Electric Cars Can Play a Key Role on the Grid

Rising Hopes that Electric Cars Can Play a Key Role on the Grid

Will electric cars one day become part of a network of rechargeable batteries that can help smooth out the intermittent nature of wind and solar power? Many experts believe so, pointing to programs in Europe and the U.S. that demonstrate the promise of vehicle-to-grid technology.

Integrated Project Delivery Management Practices: A Growing Trend in the Construction Industry

Integrated Project Delivery Management Practices: A Growing Trend in the Construction Industry

Developers and facilities owners nationwide are spearheading the Integrated Project Delivery (IPD) movement in the design and construction management industry. Due to long-term ownership and aggressive goals of high performing buildings at lower costs toward energy and potable water expenditures, an increasing number of building owners are constantly seeking new avenues to streamline risk and opportunities associated with standard contractual relationships such as Construction Manager-At Risk, Owner-Architect Agreement (AIA-B141), and Owner-Contractor Agreement (AIA-A101).

Which Is Cheaper? Nuclear or Solar

Which Is Cheaper? Nuclear or Solar

A new study reveals that nuclear energy and other traditional energy supplies like fossil fuels cost are and will continue to rise and not likely ever go back down. Meanwhile, renewable energy has achieved a “downward cost curve” over the last decade, and they are likely to continue to fall in price.
