Introduction. Energy prices and their volatility are important determinants 2. Methodology. Fractional integration is a generalization of integer integration, 3. The data. We use daily observations from the New York Mercantile Exchange (NYMEX) Highlights We test for long memory employing new developed methods. Long memories in returns and volatilities of energy prices are time-varying. Extreme events can cause long memory in volatilities of energy futures prices. Volatility persistence cannot be found in all of the time scales. We ýnd new evidence that energy prices display long memory and that the particular form of long memory is anti-persistence, characterized by the variance of each series being dominated by high frequency (low wavelet scale) components.

Time Frames. Choose from one of two time-frames from the drop-down list found in the data table's toolbar: Intraday - Intraday prices by commodity will always show prices from the latest session of the market. The 's' after the last price indicates the price has settled for the day. Energy futures quotes. Energy futures represent contracts to either buy or sell one of the fossil fuels or products related to them at a predetermined future date and price. Futures contracts are used by investors to reduce their exposure to price fluctuations of the underlying assets. Daily wholesale and retail prices for various energy products are shown below, including spot prices and select futures prices at national or regional levels. Prices are updated each weekday (excluding federal holidays), typically between 7:30 and 8:30 a.m. This page is meant to provide a snapshot of selected daily prices only.

The energy sector has probably undergone more rapid change in the last ten years than in the previous fifty. In a matter of a decade, shale gas production in the US increased by more than a factor of ten, taking US gas imports to their lowest level since the early 80s. Solar costs have come down so considerably that solar as cheap as regular grid electricity in some parts of the world, despite
