There are two figures which matter here: one is the energy that ends up in the thing you are accelerating. This is just given by
$$\frac{m_P \Delta v^2}{2}$$
Where $m_P$ is the mass of the thing, and $\Delta v$ is the change in velocity (I am tacitly assuming that this kinetic energy is relative to someone for whom the object is initially at rest).
The second, more frightening figure, is how much energy you need to put into the thing to get this $\Delta v$. If you're using a rocket to do that, then you're subject to the Tsiolkovsky rocket equation (all fashionable rocket scientists have a tattoo of this):
$$\Delta v = v_e \ln \frac{m_0}{m_f}$$
Where $v_e$ is the exhaust velocity of your rocket, $m_0$ is the initial mass and $m_f$ is the final mass. We can make this a bit more complicated and useful:
$$\Delta v = v_e \ln \frac{m_P + m_B + m_F}{m_P + m_B}$$
Here:
- $m_P$ is the payload mass;
- $m_B$ is the 'dry', unfueled mass of the booster;
- $m_F$ is the fuel mass.
You can make things better and yet more complicated by having several boosters some of which you throw away on the way to avoid carting their dry mass around. I won't do that.
You can rearrange this thing to get
$$m_F = (m_P + m_B)\left(e^{\frac{\Delta v}{v_e}} - 1\right)$$
So you can then plug numbers into that to work out what fuel mass you need. Obviously you want to make $m_B$ as tiny as you can and $v_e$ as huge as you can, but there are practical limits.
Once you know $m_F$ you're almost there. From the point of view of the rocket what you're doing is sitting in the back of it and throwing fuel out of the back with $v_e$. I always think of this in terms of a 'pebble rocket' where a person just sits at the back of the rocket, throwing pebbles from a big pile they have to hand: pebble rockets are useful because you can see what the energy is easily, and also because they make clear that the rocket can keep accelerating way beyond $v_e$ which is something people often do not understand. So the kinetic energy you are imparting to the fuel is
$$\frac{m_F v_e^2}{2}$$
But this is only the kinetic energy: you're also making the exhaust very hot usually, which heat is just radiated away into space. I'm not quite sure how to calculate the efficiency of rocket engines, but it's probably not that high.
However, the above formulae should be enough to plug some numbers into to get the things you want. The one thing you have to guess is $v_e$. I believe that $v_e \approx 5000\,\mathrm{m/s}$ is good-but-plausible for chemical rockets: you can do better with ion drieves etc.
