Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.
Obama Administration Releases Roadmap for Solar Energy Development on Public Lands
WASHINGTON, D.C. - As part of President Obama's all-of-the-above energy strategy, the Department of the Interior, in partnership with the Department of Energy, will publish the Final Programmatic Environmental Impact Statement (PEIS) for solar energy development in six southwestern states—Arizona, California, Colorado, Nevada, New Mexico, and Utah. The final Solar PEIS represents a major step forward in the permitting of utility-scale solar energy on public lands throughout the west.
Today's announcement builds on the historic progress made in fostering renewable energy development on public lands. When President Obama took office, there were no solar projects permitted on public lands; since 2009, Interior has approved 17 utility-scale solar energy projects that, when built, will produce nearly 5,900 megawatts of energy—enough to power approximately 1.8 million American homes. Thanks to steps already taken by this administration, renewable energy from sources like wind and solar have doubled since the President took office.
The Solar PEIS will serve as a roadmap for solar energy development by establishing solar energy zones with access to existing or planned transmission, the fewest resource conflicts and incentives for development within those zones. The blueprint's comprehensive analysis will make for faster, better permitting of large-scale solar projects on public lands.
“This blueprint for landscape-level planning is about facilitating faster, smarter utility-scale solar development on America's public lands,” said Secretary of the Interior Ken Salazar. “This is a key milestone in building a sustainable foundation for utility-scale solar energy development and conservation on public lands over the next two decades.”
“Developing America's solar energy resources is an important part of President Obama's commitment to expanding American-made energy, increasing energy security, and creating jobs,” said Energy Secretary Steven Chu. “This new roadmap builds on that commitment by identifying public lands that are best suited for solar energy projects, improving the permitting process, and creating incentives to deliver more renewable energy to American homes and businesses.”
The Solar PEIS planning effort has focused on identifying locations on Bureau of Land Management (BLM) lands that are most suitable for solar energy development. These areas are characterized by excellent solar resources, good energy transmission potential, and relatively low conflict with biological, cultural and historic resources. The Final PEIS identifies 17 Solar Energy Zones (SEZs), totaling about 285,000 acres of public lands, as priority areas for utility-scale solar development, with the potential for additional zones through ongoing and future regional planning processes. The blueprint also allows for utility-scale solar development on approximately 19 million acres in “variance” areas lying outside of identified SEZs. In total, the Final PEIS estimates a total development of 23,700 megawatts from the 17 zones and the variance areas, enough renewable energy to power 7 million American homes.
“Input from stakeholders has been extremely valuable throughout this process,” said Acting BLM Director Mike Pool. “Their comments have helped to refine the zones to make sure they're ‘smart from the start', to improve the transmission analyses and to build effective incentives into this blueprint for solar development."
Key elements of the Final Solar PEIS:
Establishes an initial set of 17 Solar Energy Zones on 285,000 acres across 6 Western States;
Outlines a process for industry, the public and other interested stakeholders to propose new or expanded zones; efforts already underway include California's Desert Renewable Energy Conservation Plan and the West Chocolate Mountains Renewable Energy Evaluation, Arizona's Restoration Energy Design Project, and other local planning efforts in Nevada and Colorado;
Includes strong incentives for development within zones, including faster and easier permitting, improved mitigation strategies, and economic incentives;
Sets a clear process that allows for development of well-sited projects on approximately19 million acres outside the zones;
Protects natural and cultural resources by excluding 78 million acres from solar energy development;
Identifies design features (best practices) for solar energy development to ensure the most environmentally responsible development and delivery of solar energy; and
Establishes a framework for regional mitigation plans and a strategy for monitoring and adaptive management; the first mitigation pilot for the Dry Lake Solar Energy Zone is already underway.
In support of more detailed system-level analyses of transmission needs, the BLM is engaged in ongoing transmission planning efforts, including through the Transmission Expansion Planning Policy Committee and the Western Electricity Coordination Council's transmission study.
The July 27 Federal Register Notice of Availability for the Final PEIS will begin a 30-day protest period, after which Secretary Salazar may consider adopting the document through a Record of Decision. The BLM released the Draft Solar PEIS in December 2010, and in response to the over 80,000 comments received from cooperating agencies and key stakeholders, issued a Supplement to the Draft Solar PEIS in October 2011.
