The initial cost of an incandescent bulb is small compared to the cost of the energy it uses over its lifetime. Incandescent bulbs have a shorter life than most other lighting, an important factor if replacement is inconvenient or expensive. Some types of lamp, including incandescent and fluorescent, emit less light as they age; this may be an inconvenience, or may reduce effective lifetime due to lamp replacement before total failure. A comparison of incandescent lamp operating cost with other light sources must include illumination requirements, cost of the lamp and labor cost to replace lamps (taking into account effective lamp lifetime), cost of electricity used, effect of lamp operation on heating and air conditioning systems. When used for lighting in houses and commercial buildings, the energy lost to heat can significantly increase the energy required by a building's air conditioning system. During the heating season heat produced by the bulbs is not wasted, although in most cases it is more cost effective to obtain heat from the heating system. Regardless, over the course of a year a more efficient lighting system saves energy in nearly all climates.
What are some factors to consider in calculating operating costs of lighting?
A: illumination requirements, cost of the lamp and labor cost to replace lamps (taking into account effective lamp lifetime), cost of electricity used

The morning after the election, the major candidates were neck and neck. It was clear that the result in Ohio, along with two other states who had still not declared (New Mexico and Iowa), would decide the winner. Bush had established a lead of around 130,000 votes but the Democrats pointed to provisional ballots that had yet to be counted, initially reported to number as high as 200,000. Bush had preliminary leads of less than 5% of the vote in only four states, but if Iowa, Nevada and New Mexico had all eventually gone to Kerry, a win for Bush in Ohio would have created a 269269 tie in the Electoral College. The result of an electoral tie would cause the election to be decided in the House of Representatives with each state casting one vote, regardless of population. Such a scenario would almost certainly have resulted in a victory for Bush, as Republicans controlled more House delegations. Therefore, the outcome of the election hinged solely on the result in Ohio, regardless of the final totals elsewhere. In the afternoon Ohio's Secretary of State, Ken Blackwell, announced that it was statistically impossible for the Democrats to make up enough valid votes in the provisional ballots to win. At the time provisional ballots were reported as numbering 140,000 (and later estimated to be only 135,000). Faced with this announcement, John Kerry conceded defeat. Had Kerry won Ohio, he would have won the election despite losing the national popular vote by over 3 million votes, a complete reversal of the 2000 election when Bush won the presidency despite losing the popular vote to Al Gore by over 500,000 votes.
What was Ken Blackwell waiting for that hadn't been counted yet?
A: unanswerable

Russell's ministry, though Whig, was not favoured by the Queen. She found particularly offensive the Foreign Secretary, Lord Palmerston, who often acted without consulting the Cabinet, the Prime Minister, or the Queen. Victoria complained to Russell that Palmerston sent official dispatches to foreign leaders without her knowledge, but Palmerston was retained in office and continued to act on his own initiative, despite her repeated remonstrances. It was only in 1851 that Palmerston was removed after he announced the British government's approval of President Louis-Napoleon Bonaparte's coup in France without consulting the Prime Minister. The following year, President Bonaparte was declared Emperor Napoleon III, by which time Russell's administration had been replaced by a short-lived minority government led by Lord Derby.
What political party wasn't Russells ministry?
A:
unanswerable
