Why does she hate the environment so? New York Times:

AMBOY, Calif. โ€” Senator Dianne Feinstein introduced legislation in Congress on Monday to protect a million acres of the Mojave Desert in California by scuttling some 13 big solar plants and wind farms planned for the region.
But before the bill to create two new Mojave national monuments has even had its first hearing, the California Democrat has largely achieved her aim. Regardless of the legislationโ€™s fate, her opposition means that few if any power plants are likely to be built in the monument area, a complication in Californiaโ€™s effort to achieve its aggressive goals for renewable energy.
Developers of the projects have already postponed several proposals or abandoned them entirely. The California agency charged with planning a renewable energy transmission grid has rerouted proposed power lines to avoid the monument.
โ€œThe very existence of the monument proposal has certainly chilled development within its boundaries,โ€ said Karen Douglas, chairwoman of the California Energy Commission.
For Mrs. Feinstein, creation of the Mojave national monuments would make good on a promise by the government a decade ago to protect desert land donated by an environmental group that had acquired the property from the Catellus Development Corporation.
โ€œThe Catellus lands were purchased with nearly $45 million in private funds and $18 million in federal funds and donated to the federal government for the purpose of conservation, and that commitment must be upheld. Period,โ€ Mrs. Feinstein said in a statement.
The federal government made a competing commitment in 2005, though, when President George W. Bush ordered that renewable energy production be accelerated on public lands, including the Catellus holdings. The Obama administration is trying to balance conservation demands with its goal of radically increasing solar and wind generation by identifying areas suitable for large-scale projects across the West.
