  In this study we synthesize the results of four previous studies on the
global energetics of solar flares and associated coronal mass ejections (CMEs),
which include magnetic, thermal, nonthermal, and CME energies in 399 solar M
and X-class flare events observed during the first 3.5 years of the Solar
Dynamics Observatory (SDO) mission. Our findings are: (1) The sum of the mean
nonthermal energy of flare-accelerated particles ($E_{\mathrm{nt}}$), the
energy of direct heating ($E_{\mathrm{dir}}$), and the energy in coronal mass
ejections ($E_{\mathrm{CME}}$), which are the primary energy dissipation
processes in a flare, is found to have a ratio of
$(E_{\mathrm{nt}}+E_{\mathrm{dir}}+ E_{\mathrm{CME}})/E_{\mathrm{mag}} = 0.87
\pm 0.18$, compared with the dissipated magnetic free energy
$E_{\mathrm{mag}}$, which confirms energy closure within the measurement
uncertainties and corroborates the magnetic origin of flares and CMEs; (2) The
energy partition of the dissipated magnetic free energy is: $0.51\pm0.17$ in
nonthermal energy of $\ge 6$ keV electrons, $0.17\pm0.17$ in nonthermal $\ge 1$
MeV ions, $0.07\pm0.14$ in CMEs, and $0.07\pm0.17$ in direct heating; (3) The
thermal energy is almost always less than the nonthermal energy, which is
consistent with the thick-target model; (4) The bolometric luminosity in
white-light flares is comparable with the thermal energy in soft X-rays (SXR);
(5) Solar Energetic Particle (SEP) events carry a fraction $\approx 0.03$ of
the CME energy, which is consistent with CME-driven shock acceleration; and (6)
The warm-target model predicts a lower limit of the low-energy cutoff at $e_c
\approx 6$ keV, based on the mean differential emission measure (DEM) peak
temperature of $T_e=8.6$ MK during flares. This work represents the first
statistical study that establishes energy closure in solar flare/CME events.
