(CNN) -- Presidential candidates Sens. Barack Obama and John McCain are detailing their plans for solving the country's energy crisis and criticizing each other's proposals this week as they campaign in battleground states. 

Here's a look at the candidates' energy proposals: 

Overall strategy 

McCain, the presumptive GOP nominee, has proposed a national energy strategy that would rely on the technological prowess of American industry and science. 

McCain has said he would work to reduce carbon emissions 60 percent below 1990 levels by 2050. He has said he would commit $2 billion annually for 15 years to advance clean coal technology. 

He also has pledged to oppose a windfall profits tax on oil companies that, according to his campaign Web site, "will ultimately result in increasing our dependence on foreign oil and hinder investment in domestic exploration." 

McCain also believes the U.S. needs to deploy SmartMeter technologies, which collect real-time data on the electricity use of individual homes and businesses. 

Meanwhile, Obama laid out his comprehensive energy plan Monday in Lansing, Michigan. 

"If I am president, I will immediately direct the full resources of the federal government and the full energy of the private sector to a single, overarching goal -- in 10 years, we will eliminate the need for oil from the entire Middle East and Venezuela," the presumptive Democratic nominee told a crowd. 

Obama's plan also would invest $150 billion over the next 10 years and leverage billions more in private capital to build a new energy economy that he said would harness American energy and create 5 million new jobs.  QUESTIONS:
