Task 1. Calculate the consumption values and fill in the gaps in the table, given that the global fuel consumption across all types of primary energy was 557.10 exajoules in 2020. Calculations - rounded to two decimal places.

Table 1 - Fuel consumption by types of primary energy in individual countries of the world and the world as a whole in 2020 (in exajoules)

| Country | Oil | Gas | Coal | Nuclear  energy | Hydro-  energy | Renewable  sources | Share of  global  consumption, $\%$ |
| :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: |
| USA | $\boldsymbol{?}$ | 29.95 | 9.20 | 7.39 | 2.56 | 6.15 | 15.76 |
| Russia | 6.39 | $\boldsymbol{?}$ | 3.27 | 1.90 | 1.89 | 0.04 | 5.08 |
| Germany | 4.21 | 3.15 | 1.84 | 0.57 | 0.17 | $\boldsymbol{?}$ | 2.14 |
| World as a whole | 174.20 | 137.62 | 151.42 | 23.98 | 38.16 | 31.71 | 100 |
Task 1. Using the conditions of the problem and the data from the table, we find how many exajoules the primary energy consumption in the USA, Germany, and Russia constituted. We subtract from this sum the consumption of all types of fuel except the one we are looking for, and in the remainder, we get the desired value.

USA: 557.1 x 0.1576 = 87.798. The amount of oil consumption: $87.80 - (29.95 + 9.20 + 7.39 + 2.56 + 6.15) = 87.80 - 55.26 = $ $32.54$.

Germany: $557.1 \times 0.0215 = 11.98 . \quad 11.98 - (4.21 + 3.15 + 1.84 + 0.57 + 0.17) = 11.98 - \quad 9.77 = 2.21$

Russia: $557.1 \times 0.0508 = 28.30 \quad 28.30 - (6.39 + 3.27 + 1.90 + 1.89 + 0.04) = 28.30 - 13.49 = 14.81$
