Wind Vision

About

In support of the President’s strategy to diversify our nation’s clean energy mix, an elite team of researchers, academics, scientists, engineers, and wind industry experts revisited the findings of the Energy Department’s 2008 20% Wind by 2030 report and built upon its findings to conceptualize a new vision for wind energy through 2050.

The Wind Vision Report takes America’s current installed wind power capacity across all facets of wind energy (land-based, offshore, and distributed) as its baseline—a capacity that has tripled since the 2008 release of the Energy Department’s 20% Wind Energy by 2030 report—and assesses the potential economic, environmental, and social benefits of a scenario where U.S. wind power supplies 10% of the nation’s electrical demand in 2020, 20% in 2030, and 35% in 2050. The Wind Vision Report builds upon the continued the success of the wind industry to date and quantifies a robust wind energy future.

All-Electric Vehicles

Tesla Model S

All-electric vehicles (EVs) run on electricity only. They are propelled by one or more electric motors powered by rechargeable battery packs. EVs have several advantages over vehicles with internal combustion engines (ICEs):

  • Energy efficient. Electric vehicles convert about 59%–62% of the electrical energy from the grid to power at the wheels—conventional gasoline vehicles only convert about 17%–21% of the energy stored in gasoline to power at the wheels.*
  • Environmentally friendly. EVs emit no tailpipe pollutants, although the power plant producing the electricity may emit them. Electricity from nuclear-, hydro-, solar-, or wind-powered plants causes no air pollutants.
  • Performance benefits. Electric motors provide quiet, smooth operation and stronger acceleration and require less maintenance than ICEs.
  • Reduce energy dependence. Electricity is a domestic energy source.

STATEMENT: Secretary of Energy Should Embrace America’s Clean Energy Future

Statement - December 13, 2016

WASHINGTON (DECEMBER 13, 2016)– According to multiple media reports, President-elect Donald Trump has chosen Governor Rick Perry to lead the Department of Energy. Perry was governor of Texas from 2000 to 2015, and twice ran for president of the United States.

As Secretary of Energy, he would lead the Department’s mission to “ensure America’s security and prosperity by addressing its energy, environmental and nuclear challenges through transformative science and technology solutions.” The Secretary of Energy oversees a budget of $29.6 billion (in 2016), including $10.7 billion for all-of-the-above science and technology.

Last week, several reports revealed that the Trump transition team sent a request seeking names of people within the agency who work on climate and clean energy.

Following is a statement from Jennifer Layke, global director of WRI’s Energy Program:

“Governor Perry comes from a state long-associated with the oil industry, but he also has a successful track record of promoting wind power. When Perry took office as governor, Texas had 116 megawatts of wind power, but it now boasts 18,000 megawatts, making it the country’s largest wind producer. If the incoming Secretary truly wants to boost America’s economy, health and security, he should look no further than extending the Department’s commitment to clean, renewable energy.

“The shift to clean energy is well underway and already employing hundreds of thousands of people across the country, including in rural communities. Wind and solar power have been the largest source of new electricity in the U.S. in recent years. The cost to install solar power has fallen by more than 70 percent over the last decade. Wind power currently supplies 4.7% of U.S. electricity and employs more than 88,000 Americans. That’s why states from Texas to Maine and Iowa to Florida are all investing in renewable energy.

Investing in Infrastructure? Don't Forget the Electric Grid

One of the initiatives on President-elect Donald Trump's agenda for his first 100 days in office is a plan that would spur $1 trillion in infrastructure investment over 10 years.

Along with fixing America's dilapidated roads, bridges, transit and airports, the plan envisions spending $52 billion in taxpayer money on electricity infrastructure, with a presumed emphasis on integrating advanced “smart grid” technologies. While many consumers might see this as just another technology rollout that could be best left to the private sector and the free market, leaving the future of the electricity grid to chance should not be an option.

To maximize the potential benefits of a multibillion-dollar smart grid investment, a closer examination of smart grid technology and policy is needed.

A smart grid is an electric grid that connects electricity producers to consumers in new ways, including allowing for electricity and information to flow not just from the producers, but back to them as well. It includes the various pieces of equipment and devices that are used to produce, deliver and monitor the electricity that keeps America's lights on.

Wind Turbine Technologies

Wind Turbine Technologies

The purpose of this report is to give investors a better idea of which turbine is suitable for a particular setting and to provide a new outlook on vertical-axis wind turbines. Vertical-axis wind turbines are more compact and suitable for residential and commercial areas while horizontal-axis wind turbines are more suitable for wind farms in rural areas or offshore. However, technological advances in vertical-axis wind turbines that are able to generate more energy with a smaller footprint are now challenging the traditional use of horizontal wind turbines in wind farms. Wind technology has grown substantially since its original use as a method to grind grains and will only continue to grow.

Renewable Energy Potential of India

India in continentThis report gives an overview of the renewable energies market in India. We look at the current status of renewable markets in India, the energy needs of the country, forecasts of consumption and production, and we assess whether India can power its growth and its society with renewable resources.

Integrating Wind And Solar Energy In India For A Smart Grid Platform

This paper proposes that integration of enhanced electrical capacity realized through a large-scale integration of renewable energy resources, such as wind and solar energy, in the Indian electrical grid can lead to a smarter grid platform. This will ensure increased efficiency, reliability, and security, as well as a dynamic programable renewable resource mobilization in India leading to energy independence and an electrical grid that is much more reliable, secure, efficient, and greener.

Impact of Climate Change on California's Water Supply

California is in the midst of a water crisis. By consensus estimates, climate change is poised to intensify this crisis in the coming years. Our water delivery and conservation strategies are outdated and structurally failing. California’s population is projected to rise at an alarming rate. More people mean less available water.
How should policy makers and water planners tackle these issues?

Planning for Home Renewable Energy Systems

Planning for a home renewable energy system is a process that includes analyzing your existing electricity use, looking at local codes and requirements, deciding if you want to operate your system on or off of the electric grid, and understanding technology options you have for your site. | Photo courtesy of Thomas Kelsey/U.S. Department of Energy Solar Decathlon

Maybe you are considering purchasing a renewable energy system to generate electricity at your home. Although it takes time and money to research, buy, and maintain a system, many people enjoy the independence they gain and the knowledge that their actions are helping the environment.

A renewable energy system can be used to supply some or all of your electricity needs, using technologies like:

  • Small solar electric systems
  • Small wind electric systems
  • Microhydropower systems
  • Small hybrid electric systems (solar and wind).

Planning for a home renewable energy system is a process that includes analyzing your existing electricity use (and considering energy efficiency measures to reduce it), looking at local codes and requirements, deciding if you want to operate your system on or off of the electric grid, and understanding technology options you have for your site.

If you're designing a new home, work with the builder and your contractor to incorporate your small renewable energy system into your whole-house design, an approach for building an energy-efficient home.
