The use of renewable energy is not new. Five generations (125 years) ago, wood supplied up to 90 percent of our energy needs. Due to the convenience and low prices of fossil fuels, wood use has fallen. Now, the biomass which would normally present a disposal problem is converted into electricity (e.g., manufacturing wastes, rice hulls, and black liquor from paper production). Historically, low fossil fuel prices, especially for natural gas, have made growth difficult for renewable fuels. The deregulation and restructuring of the electric power industry could have a major impact on renewable energy consumption. Demands for cheaper power in the short term would likely decrease demand for renewable energy, while preferences for renewables included in some versions of proposed electricity restructuring legislation would breathe new life into this industry. Use of renewables in the United States is not currently expected to approach that of the major fuels, and due to their limitatious (e.g., their intermittent nature-cloudy days have no solar gain, quiet days mean no wind blows to drive wind turbines, dams are primarily for flood control, so hydroelectricity production varies as dams' water levels change), renewables may never provide "the" answer to all energy problems. Around the world, renewable energy is proving to be of great value. In 2005, about 6.1 Quadrillion Btu (Quads) of U.S. energy came from renewable fuels. Each of the energy sources we use is measured, purchased, and sold in a different form. Many units of measurement are used to measure the energy we use each day. From 1996 to 2005, the trend of the consumption from renewable energy was ______. A．increasing B．decreasing C．irregular D．not mentioned

While three of them, including Lehman Brothers, take a dim view of the prospects for American shares, the other four have either marginally increased their allocations, or have maintained them at the same levels as in the previous quarter. Lehman Brothers seems to have decided that the prospect for German shares is better than it is for American ones. Its allocation for American equities dropped by seven percentage points, to 45% of its equity holdings; while its German share portfolio increased by six percentage points, to 11%. Lehman's share allocation to America has dropped, even as its overall equity holdings have increased. Daiwa and Standard Life are the other two that have cut back on American equities. But Credit Suisse continues to be a cheerleader for American shares. Following its ten percentage-point increase in the third quarter, the Swiss firm increased its exposure to American equities once again in the fourth quarter. Commerz International appears to share Credit Suisse's bullish outlook: its American equity holdings have increased by four percentage points, to 490. Julius Baer is extremely bullish on American equities, with 60% of its equity funds parked there. But the average American equity holdings, among our institutional investors dropped by a percentage point in the fourth quarter. British equities seem to have become attractive—all our investors have increased their allocations. Credit Suisse, which in the third quarter cut its investment in British shares, appears to have changed its mind. It has increased its allocation by four percentage points, taking the total to 9%. On the other hand, Japanese shares have been given the thumbs-down: all our investors save Julius Baer (unchanged) and Credit Suisse (slightly up) have moved funds out of Japanese equities. It is a relatively similar story for Japanese bonds, where everybody apart from Commerz International has either dropped their yen-denominated bond holdings, or kept them unchanged. Robeco Group seems decidedly bearish, for it has sharply, cut its allocation, from 24% to 15%. Lehman Brothers, appears to have got the timing right, by raising its allocation of dollar-denominated bonds in the fourth quarter. Its increase was followed by the Fed interest-rate cut on January 3rd. Will Lehman's bearish timing prove right for American shares, too？ Lehman Brothers______. A．has increased its equity and bond allocation in America B．pays less attention to the equity holdings because of the American economy's slowdown C．is pessimistic about the American prospect and cautious about its allocation D．is as bearish as other institutional investors
