That depends on what you mean by space. LEO to Geosynchronous orbit is still a lot more than 1% of energy to orbit.
Anyway, orbit is only 17,000 MPH which is way to slow to go travel to the next star. Traveling at at 17,000 mph would take about 40,000 years to travel one light year. The good news is you slowly accelerate in space over a long time, so smaller high efficiency engines would work just fine. The bad news is the closet star is over 4 light years from earth.
So getting something the size of the space shuttle to the next star in 1,000 years would take 2x (168^2) as much energy as it takes to get to LEO. ~56,500 * 2.2 * 10^12J = ~10^17 jules for comparison that's ~28 thousand megawatt hours.
