Objections to banning the use of incandescent light bulbs include the higher initial cost of alternatives and lower quality of light of fluorescent lamps. Some people have concerns about the health effects of fluorescent lamps. However, even though they contain mercury, the environmental performance of CFLs is much better than that of light bulbs, mostly because they consume much less energy and therefore strongly reduce the environmental impact of power production. LED lamps are even more efficient, and are free of mercury. They are regarded as the best solution in terms of cost effectiveness and robustness.
Is the environmental performance of CFLs better or worse than that of incandescents?
better

Yugoslavia organized the Yugoslav People's Army (Jugoslavenska narodna armija, or JNA) from the Partisan movement and became the fourth strongest army in Europe at the time. The State Security Administration (Uprava drzavne bezbednosti/sigurnosti/varnosti, UDBA) was also formed as the new secret police, along with a security agency, the Department of People's Security (Organ Zastite Naroda (Armije), OZNA). Yugoslav intelligence was charged with imprisoning and bringing to trial large numbers of Nazi collaborators; controversially, this included Catholic clergymen due to the widespread involvement of Croatian Catholic clergy with the Ustasa regime. Draza Mihailovic was found guilty of collaboration, high treason and war crimes and was subsequently executed by firing squad in July 1946.
What was formed as the new secret police?
