German power exports still more valuable than imports - 100% renewable - Renewables International

German power exports still more valuable than imports - 100% renewable - Renewables International | Sustainable Energy | Scoop.it
Last year, the electricity Germany exported was 6.3% more valuable per unit than the power it imported – the exact opposite of the narrative that Germany is dumping excess renewable electricity on neighboring countries at low cost. France faces a particularly dire imbalance financial; German electricity is 24.4 percent more valuable..

Household Electric Car Chargers: What You Need To Know

Household Electric Car Chargers: What You Need To Know | Sustainable Energy | Scoop.it

While you may have an outlet in your garage ready for your Level 1 charger, you might be weary of the wiring. In that case, you’ll want to have an electrician look things over. They will need to make sure the outlet you’ve selected is on a dedicated circuit, serving no other outlets or switches. The electrician should also make sure the electrical panel will have enough capacity to deal with charging your car.

Continental Will Help Make Electric Vehicles Go Mainstream

Continental Will Help Make Electric Vehicles Go Mainstream | Sustainable Energy | Scoop.it
Toyota is buying electric powertrains from Tesla for its RAV4 EV. Three years ago, it was BMW buying powertrains from AC Propulsion. What's wrong with this picture? It's not normal for an established automaker to source major components to unproven start-ups, but those days are over now that traditional auto suppliers have moved into electric territory.

Depending on their commitment to electric mobility, some car manufacturers may chose to do everything by themselves, like Nissan did. Or OEMs can make a joint-venture with a supplier, Smart being a good example, or buy from a well-regarded auto supplier. That's what Renault did for its Kangoo and Fluence Z.E. models, which both use an electric motor supplied by Continental. As a leading auto supplier, Continental, often called Conti for short, is mostly known among drivers for its tires. But to auto companies, Conti builds the turbo on Ford's latest Ecoboost engine, and it's a world-leader in safety technologies (braking and chassis electronics). Some people may also remember that Conti had partnered with A123 Systems with the hope to provide the battery pack for the Chevrolet Volt.

Grid blackout threat weighs on renewables take up - EurActiv

Grid blackout threat weighs on renewables take up - EurActiv | Sustainable Energy | Scoop.it

The policy chief of Europe’s electricity industry association has told EurActiv that Europe will have to slow down its integration of renewable energies or risk power cuts and systems instability because of the slow pace of cross-border grid improvements.

 

“Either you go very fast in the transition - which is impossible [because] smart grids are expensive and the storage is not there in the needed scope – or you diminish the speed for integrating renewables into the system,” Susanne Nies of Eurelectric told EurActiv in a phone interview.

Changes in the Electrical and Micro Grid

Changes in the Electrical and Micro Grid | Sustainable Energy | Scoop.it

Microgrids are becoming a worldwide phenomenon. Currently an estimated $4.5 billion market in the US alone with 1,459 MW online and 1,122 MW in planning or development, the microgrid market is expected to continue to grow as the world demands ever more electricity usage and the grid struggles to keep up. The truth is that the traditional grid was not built to cope with the extraordinary level and fluctuations of present-day demand, and microgrids present the perfect solution. The question (to the utilities) is whether we are ready to embrace the change and adapt.

CPUC Undercounts Energy Savings That Can Offset The Need For New Power Plants

CPUC Undercounts Energy Savings That Can Offset The Need For New Power Plants | Sustainable Energy | Scoop.it

The Commission’s decision relies on 3,000 megawatts of energy efficiency in the base case, which is the equivalent of six giant power plants. Instead, the CPUC should have relied on the California Energy Commission’s best estimate of the actual amount of cost-effective energy efficiency expected, which is equal to 11 giant power plants, or approximately 5,500 megawatts of energy savings. 

As the difference between the red line and the blue line in the graph below shows, the CPUC voted today to undercount efficiency by approximately 2,500 megawatts.  That could lead to the authorization of unneeded power plants, instead of relying on our state’s abundant energy resource that saves customers money and helps clean the air: energy efficiency.

Hans De Keulenaer's insight:

Interesting story how energy efficiency can/should be used as a planning tool in licencing new power stations.

Smart Grid: Isn't it time for the grid to go underground?

Smart Grid: Isn't it time for the grid to go underground? | Sustainable Energy | Scoop.it
Smart Grid - A growing chorus of East Coasters is crying for the distribution grid to be buried underground to forestall outages from giant storms like Hurricane Sandy.

I understand the problems and concerns about undergrounding... yet I believe that, as an industry, we overestimate the cost of burial. And that's because we underestimate the potential for cooperation and collaboration with other utilities to do joint undergrounding.

The Outlook for Energy: A view to 2040

The Outlook for Energy: A view to 2040 | Sustainable Energy | Scoop.it

In 2040, what types of energy will the world use, and how much? How will new technologies, efficiencies and policies impact the market?

The electricity generation sector is essential to meeting modern energy needs. Utilities and other electricity producers transform different types of primary energy – everything from natural gas to coal to wind and hydroelectric power – into electricity to be used in homes and businesses. Through 2040, global demand for electricity will continue to rise steeply, as the fuels used for electricity generation continue to shift to lower-carbon sources, such as natural gas, nuclear and renewables.

With a Jolt From Tesla, a More Electrifying Utility

Toyota and Tesla team up for launch of electric RAV4 in California.



With the plus-size battery that makes it all possible comes a hefty price: $50,610, before a $7,500 federal credit and a $2,500 California rebate; Toyota expects to announce a lease plan this month. The EV is equipped with about the same level of amenities as the gasoline-powered RAV4 Limited V-6 model, which costs $31,279. (Well, there's no leather upholstery, but the EV borrows more efficient headlamps from Lexus.)

Still, $40,000 buys a Tesla-brewed Toyota that offers generous space for passengers and cargo, and even if you commute alone, there's no need to feel guilty, because there's no tailpipe fouling the atmosphere. Only 2,600 units will be made, with production wrapping up at the end of 2014. The limited run, I believe, will only heighten its appeal, earning Toyota a legion of interested customers begging the company to make more.

The contribution towards total generation from eligible renewable resources also varies seasonally. For the dates charted above, the amount of renewable generation as a percentage of the total generation within the CAISO ranges from 8% on Oct 18, 2011 to 14% on May 9, 2011.

California is trying to achieve a 33% Renewable Portfolio Standard (RPS) by 2020, with eligible resources that include wind, solar, geothermal, biomass, biogas, and “small hydro”, which translates roughly as generators under 30 MW.
