Hydro Financing Faces Hurdles

By


Hydropower supplied 8% of US electricity in 2011, and 62.5% of renewable electricity, according to federal statistics, and hydro advocates say it could provide twice as much if upgrades were made to aging power plants and new technology utilized in rivers and tidal estuaries.

But with the continuing depressed price of natural gas and looming expiration of hydro’s clean energy tax credits, prospects for taking better advantage of US water power are shrinking, financial experts told the National Hydropower Association conference in Washington DC this week. Keep reading →

How The Power Grid Is Blocking EV Adoption (And What To Do About It)

By

The charging cord for the Tesla Model S electric car

There is a hidden barrier to electric vehicles (EV) adoption – our electric grid. EVs could significantly increase peak demand and thus impact grid reliability. AMI and demand response technologies are often promoted as the solution for this uptick in peak demand. But we also need to look at other, grid-based solutions to enable broader adoption of EVs. Here are a few reasons why: Keep reading →

Three Honeywell Global Smart Grid Projects: The Law Of Large Numbers

By


Honeywell is making a major play in the smart grid and demand response world, building on its already enormous client base of more than 100 utilities – with millions of customers – that the company says has already resulted in more than a gigawatt in saved electricity.

The company is building out a global footprint in smart grid with both large and small projects it says will underpin efficiency efforts and support end-user control of the systems that consume energy. Keep reading →

On A Roll, Wind Developments Continue Cropping Up

By


Renewable energy developments seem to be sprouting up everywhere in recent months.

Last week, Western Wind Energy began operating its newest 10.5 MW wind-solar project in Arizona while on Tuesday Duke Energy announced plans to build its fifth wind power project in Texas. Duke Energy also recently announced plans to build its second wind farm in Pennsylvania this year. Read more: Duke Energy Adds Wind. Keep reading →

Fusion For The Future

By


America faces a series of significant challenges regarding how we produce and use energy over the next several decades. Our current energy system undermines our national security, is economically unstable, and environmentally unsustainable.

Although the recession has reduced energy demand, in the longer term the US is expected to see a 20% increase in total energy demand and a 30% increase in electricity demand by 2035. Keep reading →

The Reality Of Wind Power

By


Wind turbines cost more to operate and maintain than planned, often have poor reliability, and place costly strains on other generators warns one early wind adopter, but so far the public is willing to bear the costs.

Kevin Gaden, wholesale power director for the Municipal Energy Agency of Nebraska (MEAN) and NMPP Energy, a public power consortium covering parts of Nebraska, Iowa, Wyoming and Colorado, detailed his members’ experiences at the American Public Power Association conference in Washington last week.

Flexibility For The Future

By


What is the answer for our future energy needs? Do we focus on solar, or wind, or natural gas, or oil, or cleaner coal or nuclear? The reality is that we need to find new ways to make all of these energy sources work together if we are going to achieve the cleaner, more affordable and reliable energy mix of tomorrow.

Renewable energy will be an important component of the future energy grid and governments around the world are putting incentives in place to increase its uptake. Keep reading →
