Report: Hybrid energy systems, smart grid planning needed to boost renewables

Matched solar and wind systems could ensure steady supply of renewable energy

Staff Report

FRISCO — Smart grid planning and better energy storage could significantly boost the use of renewable energy in the U.S. according to a new report that calls for developing “hybrid” systems in which, on a broad geographic scale, one form of renewable energy is ramping up even while the other is declining.

Historically, a major drawback to the use and cost-effectiveness of alternative energy systems has been that they are too variable – if the wind doesn’t blow or the sun doesn’t shine, a completely different energy system has to be available to pick up the slack. Continue reading

Sioux Nation wants to focus on renewable energy, not dirty tar sands oil

Staff Report

FRISCO — Just a few days after responding angrily to the U.S. House vote to approve the Keystone XL Pipeline, Sioux Nation Native American leaders met with the Obama administration to explore renewable energy options.

The meeting included representatives from more than eight federal agencies and offices, including representatives from the Departments of Agriculture, Interior, Treasury, and Tribal Relations. Continue reading

Global hydropower boom poses biodiversity risks

New database to help assess impacts of planned dams

Staff Report

FRISCO — An emergent global hydropower boom will help meet the demand for low-carbon energy, but also poses environmental risks, according to experts compiling a new data base on global hydropower.

The boom is expected to double production of hydropower, but could also reduce  the number of our last remaining large free-flowing rivers by about 20 percent and pose a serious threat to freshwater biodiversity.

A new database has been developed to support decision making on sustainable modes of electricity production. An unprecedented number of dams for electricity production is currently under construction or planned worldwide, mainly in developing countries and emerging economies in South America, Southeast Asia and Africa, that also hold some of the world’s most important sites for freshwater biodiversity.  Continue reading

Let’s do offshore wind power the right way!

‘It is essential to identify where whales, dolphins and other species occur to help avoid adverse impacts and to continue to monitor their response to the construction and operation of wind turbines’

Offshore wind turbines could provide most of the power for North American cities.

Staff Report

FRISCO — Many of the conflicts between energy development and wildlife protection developed because there wasn’t enough upfront planning. Researchers with the University of Maryland say similar issues relating to offshore wind energy can be minimized with early monitoring.

“As the number and size of offshore wind developments increases, there is a growing need to consider the consequences and cumulative impacts of these activities on marine species,” said Helen Bailey, lead author and research assistant professor at the University of Maryland Center for Environmental Science’s Chesapeake Biological Laboratory.

“It is essential to identify where whales, dolphins and other species occur to help avoid adverse impacts and to continue to monitor their response to the construction and operation of wind turbines,” Bailey said. Continue reading

Study: Natural gas boom won’t slow global warming

Increase in global gas production likely to displace renewable low carbon energy

Staff Report

FRISCO — Increasing production of natural gas won’t save the world from global warming, researchers said this week.

In the long run, a global abundance of inexpensive natural gas is likely to displace not just coal, but  also lower-emitting nuclear and renewable energy technologies such as wind and solar. Inexpensive natural gas would also accelerate economic growth and expand overall energy use, the study found.

“The effect is that abundant natural gas alone will do little to slow climate change,” said lead author Haewon McJeon, an economist at the Department of Energy’s Pacific Northwest National Laboratory. “Global deployment of advanced natural gas production technology could double or triple the global natural gas production by 2050, but greenhouse gas emissions will continue to grow in the absence of climate policies that promote lower carbon energy sources.” Continue reading

FRISCO — I didn’t quite get around to reporting on the discovery of new fish-eating spider species last week, but I did cover a lot of environmental territory.

Along with climate stories in Summit Voice I wrote about the emerald ash borer invasion and hydropower for Boulderganic, and even penned a food- and environmental themed Colorado roadtrip story for the Boulder Weekly.

On a more serious note, I was the first journalist to take a close look at the City of Denver’s as-yet unpublished climate change adaptation plan, showing that life in the Mile High City could be nearly unbearable by 2050 — but also showing that making adjustments for global warming could have huge benefits for Denver by expanding green infrastructure.

Congress grapples with wind power tax credit extension

More wrangling over renewable energy, as coal barons pull out all the stops

Fossil fuel barons are sensing the end of their era, and pulling out all the stops to squeeze a few more years of profit from their toxic activities

By Bob Berwyn

FRISCO — Fossil fuel companies pulled out all the stops this week, cashing in their lobbying chips to corral the U.S. Senate into stalling a bill that would have extended for the wind production and investment tax credits.

A small group of senators who are deep in the pockets of the fossil fuel industry used a procedural vote to block a full Senate vote, eliciting a frustrated response from Sen. Michael Bennet (D-CO).

“This is yet another example of Washington not doing the work that Coloradans and the American people expect us to do,” Bennet said. “This tax extenders bill was approved by the Senate Finance Committee with strong bipartisan support. Coloradans and the American people deserve better.

“The wind tax credit is an economic driver for Colorado’s diverse energy industry. It supports thousands of jobs up and down the supply chain. Delaying this extension risks the same type of economic damage we experienced that last time the credit was allowed to expire,” he said.

Colorado generates the sixth highest percentage of power from wind of any state in the nation. It is home to several major wind energy developers and wind turbine manufacturing facilities, employing upwards of 5,000 workers statewide. Nationally, a permanent expiration of the wind production tax credit could cost as many as 37,000 jobs, according to the American Wind Energy Association.

The political maneuvering came the same day that German officials announced that the country set a new renewable energy record, with wind and solar generating enough power to meet 74 percent of the demand on Sunday, May 11.
